ENGLISH: I was a 1&1 customer for 7 years, and honestly, I regret staying that long. The service itself was okay, but the prices were always high. In my home country I now pay the same price for four times the data. What really changed my opinion was how they treat their customers. I had to leave Germany unexpectedly, and after 7 years of loyalty, they still refused to cancel my contract. They even claimed I had requested a speed change, something I never did, just to avoid letting me end the contract. It felt disrespectful and dishonest. A company that treats long-term customers like this clearly does not value them. I cannot recommend 1&1. DEUTSCH: Ich war 7 Jahre lang Kunde bei 1&1 und bereue es, so lange geblieben zu sein. Der Service war in Ordnung, aber die Preise waren immer relativ hoch. In meinem Heimatland zahle ich jetzt den gleichen Betrag für die vierfache Datenmenge. Was aber wirklich meine Meinung geändert hat, ist der Umgang mit Kunden. Ich musste Deutschland unerwartet verlassen, und trotz 7 Jahren Treue weigerte sich 1&1, meinen Vertrag zu kündigen. Stattdessen wurde behauptet, ich hätte eine Geschwindigkeitsänderung beantragt, was ich nie getan habe, nur um die Kündigung zu verhindern. Das war respektlos und unehrlich. Ein Unternehmen, das langjährige Kunden so behandelt, zeigt deutlich, dass es sie nicht wertschätzt. Ich kann 1&1 nicht empfehlen.

I want to share my frustrating experience with 1&1 regarding a mobile contract issue. Due to a misunderstanding and limited German language skills, I accidentally signed up for three mobile contracts on the same day through an online promotion. I didn’t realize that this created binding agreements. None of the SIM cards were ever activated or used—not even once. For the first year, I wasn’t charged anything, so I didn’t notice the contracts were active. Only recently, after unexpected charges appeared on my account, I discovered that the contracts were still running. I immediately contacted 1&1 and explained the situation, asking for an extraordinary cancellation. Despite the fact that: • No service was ever used, • No SIM card was activated, • The contracts were clearly accidental, • And the minimum contract duration is 2 years, 1&1 refused to cancel them early. Their response was polite but completely rigid, showing no flexibility or understanding of the situation. I find this extremely disappointing and unprofessional for a company of this size. I will continue to share my experience across platforms to raise awareness about how 1&1 handles such cases. If you value customer service and flexibility, I strongly recommend considering other providers.

Unfortunately I can't set a negative star note, even 0 would not be enough

Once you attempt to terminate a contract orderly, this company seems to switch to full-on scam mode. ​I initiated the termination for the next renewal cycle (four weeks away) directly through their app. With any legitimate business, the process should have ended right there with a simple confirmation email. ​Instead, I received a notification stating I must call them to confirm the cancellation. ​I called, politely declined the staff's several aggressive attempts to sell me other packages, and was assured a confirmation would be issued. While I was slightly annoyed by the unnecessary hassle, I still assumed I was dealing with a trustworthy company and that the matter was resolved. ​A week later, realizing I never received the confirmation, I emailed their designated cancellation address. I finally got a confirmation email a day later. The only problem: they confirmed my cancellation not for the date I requested, but for the exact same date ONE YEAR LATER, despite it being a contract that renews every four weeks. ​Happy to finally have a confirmation, I didn't scrutinize the document closely enough to notice they had simply snuck in a different digit for the year, confirming a completely different date than the one they were obligated to honor. I only discovered their deception months later when I saw they were still withdrawing money. ​When I called them out, they flatly declined to correct the issue, claiming it was my fault for not reading their confirmation thoroughly. ​I have the emails proving I terminated the contract orderly. However, I am not willing to invest any more time fighting over something that should have been a non-issue and resolved with a few simple clicks. But it looks like that's exacrly why they do what they do.
