Poor service and not protecting clients

My landline telephone provider has been debiting my business account although the same service was cancelled by way of the proper protocol in June 2018. I have personally tried to stop them improperly taking money from my business account but to no avail ... hence I raised a debit order dispute with FNB on 4 October 2018 to prevent the service provider from taking money for a service they are not providing.

FNB have been really poor in respect of keeping me informed on their progress. It is now 1 November and it seems they have done little or close to nothing as the service provider again took money from my account for November.

Very disappointed with FNB and it appears that the only way to resolve this issue is to close my account which will prevent unauthorised debits from my account.
