MTN AND MONDO ARE UNINTERESTED TO SOLVE THEIR MISTAKES

I WANT TO WARN PEOPLE AGAINST DOING CONTRACTS ONLINE, ESPECIALLY WITH MONDO AND MTN. I upgraded my MTN contract online through Mondo in January 2022. I took out an MTN contract for R449 ( MTN mega gigls L with and LG handset), but has been paying R1010.00 per month since. I've phoned the MTN call centre approximate 18 to 20 times. Everytime I phoned I get a different answer. Either it's recurrent bundles, next time I phone it will be that I'm paying R530 something for my LG handset. I was eventually put through to Mondo where an investigation was started. This, I was told will take 2 weeks, but only after a month and my 3rd phone call I was told" that the agent captured everything correct and there was no cause for a dispute. During my many calls on the 135 number to MTN , one agent told me it's a billing error by MTN. The query was closed the same day with still no answer. Another agent at the MTN shop at their head office in Roodepoort, told me that Mondo never cancelled my previous contract when I upgraded. I phone Mondo again and Chantelle informed me that it is indeed a billing error at MTN and that the "dealers ID" should be changed. With that said, even if MTN wakes up and fix their mistake, my contract will still be over R600 because of the way the Mondo agent capture my contract, which should be R449. Mondo however still doesn't acknowledge or could explain to we how a R449 contract is now over R600 and why I will be paying R50 for a handset if my online deal( of which I have send them proof) clearly says "TOTAL AMOUNT R449.00" PLEASE SORT OUT MY ACCOUNT AND CONTRACT. I WILL NOT PAY A FURTHER CENT UNTIL THIS HAS BEEN RESOLVED. I HAVE ALREADY OVER PAY BY APPROX R3000.00.
