Vodacom has the worse system and customer care service

I had an account with vodacom. I recieved a call stating that i have to pay R1621 after a struggle to cancel the contract that they renewed.. I then refused to pay the contract and afterwards i decided i will pay the account. The end of July 2018 i went to Vodacom 4u at Cape Gate ,i paid the full amount of R1621. I then recieved a call from vodacom call center stating that i did not pay my account,i told then i made the payment,they said it is not reflecting. I told them i made the payment,i even gave the the person's name whom i paid with,the lady's name is Mari. I missed placed the proof of payment,i went back to the store to asked for a reprint or a copy of my payment. Luckily for me the lady i made the payment with remembered me,she was there.. I explained my situation,she could'nt understand why it is not reflecting on the system. Mari and the Yumna who was on duty that night said they will ask Admin to trace my proof of payment. It has been more then a month i did not recieve any feed back from them. I refuse to pay another R1621 because i payed it already.

Their service is so Bad. Still awaiting on Vodacom 4u and that my payment is not reflecting on their system
