Paying R200 extra every single month

A year ago I took out a wifi contract with them, their special for R449 uncapped. I've NEVER only paid R449, I pay manually through their self service portal each month and on time, however EVERY month I get switched off for an outstanding R200 that I must pay because they are debiting an inactive account, that I've requested COUNTLESS times (they record all calls) for them to STOP doing. I pay that extra R200 EVERY month because I need to work, and my work requires WiFi. So technically I'm paying R649 every month. Your admin is putrid. The lastest agent I spoke to was Eyethu who confirmed to me that the debit order on the inactive account is cancelled, and I can continue paying manually like I've been doing. But that debit order is still not cancelled which means they will AGAIN charge me more for a mistake THEY have made. Can SOMEONE from Telkom assist who actually calls the shots? Or is this a money making scheme on Telkoms side?
