It is impossible to get help through their German-speaking bot! I have to call more than three times for it to understand me. This is an awful experience. It would be easier to write an email, but they don’t provide that option. You just have to suffer because your German pronunciation isn't perfect. And the internet connection quality is poor as well. I’m glad I can finally close my contract.Update: I finally reached customer service and told the agent, "Ich brauche Rechnungen, die älter als 13 Monate sind," but he didn’t understand me. I repeated it with the same result. Then, I suggested speaking in English, and I got a lecture about how "This is Germany, and we speak German here." I wish I didn’t understand German so I wouldn’t have to hear that! The funny thing is, the next operator he transferred me to, understood my German perfectly and helped me. But after all this, I no longer want to use this company's services.
