DOUBLE BILLING

Hi telkom.on 6 October i paid a bill of R897 to telkom per my contract and some extra data i had purchased on it.i noticed the outstanding R897 was still showing on my account.i queried this at bayside branch and took my receipt in but was told it was just a system error and it will be removed.in Oct i again purchased some data on my contract to be paid beginning of Nov.halfway through Nov my telkom sim was cut from the network due to an outstanding amount of R897 from September.i explained to telkom this had already been paid and spent ages speaking to call center and emailing everyone my proof of payment.in the end i was told it was a mistake and i just need to pay my nov bill and my account will be reconnected.i paid the balance of R937 which i also have the receipt for and my sim was not activated.when i called the call center they said it was cause i had an outstanding amount of R897 from september and until it was paid my sim would stay dead.ive emailed the proof of payment and never heard anything back.i only spend what i know i can afford to pay and telkom cant expect me to pay twice for the same bill when ive got a receipt.my case number is ***1.please fix this asap!
