Debited every month evenafter cancellation

I cancelled my account and services with Supersonic at the end of August (29th specifically) and gave my notice.

However, I am still being billed. Even after I sent a mail to the billing team last month for the same fault where they rep**** back saying they will give me credit, and yet it happens again.

I have sent countless mails querying this and receive no response.

At this point, it is just *****ing money. My account is being debited for a service I don't use and cancelled over 2 months ago.

This needs to be remedied or I will NEVER use Supersonic as a service provider again.
