Paid up account

I had a contract with Vodacom and I went into a Vodacom shop to explain to them that I couldn't afford to pay my account for a few months but I have the money know to pay it up in full, the lady then checked the system she gave me details to contact I contacted them, they gave me an amount of R2462.55 to pay and I paid it, then I was told to fax the proof of payment, so I went back to the Vodacom shop in Westgate and I asked them to please fax the proof of payment, and all this was done 14 January 2015 at 12:26, I have all my proof of payment and the fax confirmation from the Vodacom shop, and yet my name has not been cleared and they told me as soon as they get my proof of payment it will be cleared and it is more then a month later and nothing has been done.
