First of all, I am sorry that I cannot speak German. Please read my story and make a judgement on your own.

Today, I had to call the English hotline, as I am going to move to another city, and wanted to transfer my contract. After waiting for 2 hours(not joking) on the phone, I gave up and decided to try the German hotline.

I know that the Umzug can take 3 to 4 weeks. This is a stupidly long amount of time for moving, but I decided to live with that.

However, the customer representative on the phone told me to make an appointment 4 weeks later, because there is a work on the line in my new address. They said, they cannot initiate anything now, that I need to wait 4 weeks to get an appointment which will probably be for 4 weeks later. 

This isn't my first issue with Telekom. A few years ago, they couldn't fix an issue which was totally related to themselves, they sent technicians multiple times, left me without internet for a month, and they asked me to pay for the technicians and for the service that I couldn't even use. After 2 years, after I did all my part, they are not even capable of moving my internet in a proper amount of time, and they will again ask money for their amazingly useless service. 

I've worked with many other ISP 's around the world. I can safely say that I haven't seen such a terribly managed customer service. 

I wrote everything here, since nowadays, you cannot get attention unless you write something on the internet. Once my contract is over, I will never ever work with you again Telekom. Enjoy your low quality standards.
