The worst operator in the Czech Republic ... in Ja...

The worst operator in the Czech Republic ... in January I wanted to cancel a number at the branch that I have not used since the summer, I was told to stop at the end of March that I am bound by a contract that ends in April. So I went to the branch on March 27, 2020, there I was told that someone from O2 would call me, that I was there, so it could not be disturbed at the branch. They called me about 2 times, but still someone else called me. Abbreviation in the summer of July 13, 2020, I sent a notice in writing. If no answer came about a month after the delivery of the mail to O2, I went to the O2 branch again and they told me that my mother had been shooting for 2 years since April. Well, a bunch of terrible. Now I have to send one other notice in writing, and if no answer is received, it will be dealt with by a lawyer for violating a few paragraphs. We are looking after one very good lawyer, so it will be ok. We are a company that has several phone numbers at O2 and some services such as internet and TV. We cancel everything completely and go elsewhere.
