Still billing me after cancelation

I took out a LTE deal with Telkom a couple months ago

I tried phoning them to complain that my package I received via courier company was incomplete

I week went by and nobody got back to me, so I phoned them again and cancelled the deal with them

The courier company came to collect the package a day or so later and I was advise that my contract has been cancelled This was in October I have received a bill for October and November even though I don’t have a contract with them Still tried to get hold of them but with no luck.

Yesterday I have received a new bill for December When will this stop I phoned my banker to block and cancel the debit order in the hope that the billing dep will contact me and still no luck

Thank you Telkom for the awesome service I have received from you

I will never in my life take a deal with Telkom.
