Termination not possible

Dear OVH team,

ticket number 1507931149

I sent you following mail on the 20.04.2017:
Subject:invoice 67111350
Dear Support Team,
As I do not own a credit card any more I would like to cancel or do a bank transfer.
Can you please provide my your account details? Or confirm my cancelation of the account xxx@xxx.com
Thanks in advance,
BR,
Martin

I never received a feedback and I am no more using hubic since mid of 2017; I am still getting invoices from you.

I also tried to contact ovh.de. without success. I am not willing to pay the unwanted renewal - invoice HUBICEU788613. Please cancel the invoice that I can close the hubic account.

Thanks in advance and BR,

Martin
