OVER BILLED ON THEIR SYSTEM ISSUES

on the 26th of July i requested a downgrade from Compact Plus to The Family package of R309 pm plus R110 for pVR. On the 27th July which is my billing date i made a payment of R467. On the 26th of August i requested a downgrade again from Family to DStv Access for R120 plus R110 for pVr, i then paid R230. All these requests were done via self service on whatsapp. In September i checked my billing and saw an amount of over R400 i called the call centre and was advised its an error on your side the down grade wasnt captured by the system and the consultant amended it , which is strange as i had Access channells the whole month i then made a payment of R230 on the 28th September. This month( October) i made a payment of R230 on the 27th and now im told i owe R239. which is for family a package i downgraded from in August. I paid this amount as i need the services active as they were disconnected. I need that amount of R240 i paid on the 01 November to be refunded as its not my fault your system didnt record the downgrade i requested on the same self service channel that you guys always advise us to use. Customer number is ***0 A consultant by the name of Nolwazi Nzimande gave me ref number:*** on the 01 of November she then escalated the call and i was called by Zanele who asked that i send the Whatsapp conversations via email and i received this ref number via email:***4 i called your call center now and all ref numbers cant be found...the two agents i get through to are not clued up in anything.

I need my Refund ASAP
