Hello,
I was using o2 DSL M Flex internet connection. I cancelled my DSL contract on 16.01.2020 and faxed the cancellation letter on 16.01.2020. I also sent my modem to the address provided by o2 and received a confirmation that the modem was received. However, on 18.02.2020, 17.03.2020 and on 20.04.2020 money was debited from my account. I also received invoice for this (May) month. Why I still receive the invoice after the cancellation of my contract. Customer number: XXXXXXXXXX.
