Telkom does not know what they are doing

There seems to be a problem on your side about cancelling one of my phone contracts ***. I went into the store at Eastgate to cancel this number at the end of December after the contract date had expired, I was told in store that it would take up to 48 Hours to do so I sign the paper work and the assistant that was helping me sent off the paper work. It still has not been cancelled I am still receiving invoices for that Account. Since January. I received this email Monday 2015/03/23 if they really wanted to get hold of me they would have seen that I have another number with you ***. And could have contacted me on that number. But if you see the date on the email why has it taken so long for someone to try and get hold of me? I paid the amounts due on every invoice including the one for the saver7 account *** and haven't used it since December you can go back on all your records check on it. In April I phoned and spoke to the team manager Sandile Thekiso and assured me that the account would be cancelled. I asked if I would be billed for this account again and he said no. and then sent me an email sating that I would not have to pay yet I am still receiving bill
