Dear Magenta,
I really hope someone understands English here, the story is simple:
I terminated my contract in July 2019, I had 6 more months left and agreed to pay the rest of the months on August.
Which I did, on August I received a bill of all of the money that was left, and I was told it is going to be the last one.
I returned my Router box and I did everything correctly, I even have the paper the confirms the cancellation of my account
However I saw a bill of 20 Euros this month, as if I am still a costumer.
I already payed everything I need and I am not a costumer anymore, I need you to stop billing my bank account. (and getting back the money for September would be nice)
Thanks in advance
