Bad service from Telkom Bloemfontein

I had a wifi contract with Telkom for 2 years, and never received any communication that the contract was due for upgrade/cancellation. This notification, according to law, should be sent to the client 40-80 days before the contract ends.

I sent my cancellation letter through in june 2017. Since end of June 2017 until today, I have sent 5 emails and visited the Telkom offices twice regarding the cancellation of the contract. The contract is still not cancelled, no feedback or replies from Telkom, and I'm still receiving accounts.

I only have to pay pro-rata for the last 17 days of my contract (which ended according to my cancellation letter on 17 July), but I am still receiving accounts for full months (1-31 July), although the contract had to stop on the 17th of July.

Can someone please just answer me and get this off my name?

Really bad service and not a happy client!
