Enough is enough!

One star rating is still too high! After a miserable experience in Nepic attempting to migrate my account unsuccessfully to SuperSonic and despite multiple requests to stop the debit order I originally authorised in favour of Nepic, my account is still being debited. In the meanwhile I have moved to a new service provider and am already in my second month of service with the new service provider. So why is Nepic still taking my money? And refusing to reply to my e-Mail queries?
