Very very low level of service and billing errors

I'm very disappointed in the low levels of service I'm receiving from Telkom

3 months ago I did change of ownership on 2 accounts, I supp**** my bank details and the consultant told me it's all done and will reflect soon, this week I find out that the change of ownership has still not been done and all my accounts are in arrears and I had to pay payment rejection fees

7 months ago I switched my landline to a biz talk contract and also found out this week that it actually isn't on biz talk

I also found out that the hunting facility was not cancelled so I have been paying for it all this time

I need this matter resolved and all my money owed to me credited of my account or I'll be forced to switch to VOIP

Thanks
