Mtn bad contract deals and debit errors !!!

Mtn customer care is terrible. I regret taking a second contract with them. It’s been 3 months now into the contract and I still haven’t got what I signed up for. I keep calling every week and keep being told it has been resolved whereas it hasn’t ! I took a contract on the 1st of June 2019, Made for Me S for R249 p/m x 24. In the package : Samsung A20 with 1 GB ANYTIME + 1 NIGHTTIME DATA , 100 min; 25 mtn min; 100 sms + FREE 20 GB DATA ANYTIME ONCE OFF valid for 30 days and 14 GB ENTERTAINMENT PASS. Instead I got 350mb package and was charged prorata to it up. In July they assigned the correct data 1gb day 1gb night , but no bonus data (20gb once off and 14gb entertainment pass) as promised on the pamphlet. And they haven’t attempted to reimburse for giving me the wrong package in June !!!!! Instead they make me repeat myself to countless agents who claim to escalate the matter and I just get a text saying issue resolved, call if matter persists . It’s 3 months in to the contract ! Still being billed random amounts and not the correct one ! I have 2 contacts with mtn a sim contract for R210 and this new MADE FOR ME S for R249, which totals to R459 but they debited R549!!!!! The worst part is I called mtn to notify them of the error before the debit goes off 3/4 days before the debit as I received an sms notifying of the debit amount due. And still the wrong amount was debited !!! Mtn call center agents all kept asking me to email the contract or trying to break now why I got the package that wasn’t advertised. Instead solving the matter at hand, and the package was for the 1st of June as per the pamphlet . Which was that the error was on MTN’s side for advertising a package bundle that their systems hadn’t updated yet. On my end I signed the contract but the contract didn’t state the package entails so therefore I signed with what the pamphlet advertised, that’s what I signed up for that is what is what I should get , I don’t even know why I had to call over 8x and get excuse after excuses being told that it’s the store’s error whereas the error was on mtn system and advertising not corresponding. My time and effort going All the way from Orange grove to Fourways just to sort out this pending issue which still isn’t solved is getting ridiculous!!!!! And I want the R90 that I was overdebited with back in my account, the error was on MTN’s side for such careless and mishandling of contracts . It’s beyond disappointing. If I could I would give this a negative rating I would. In fact I want mtn never to debit from my account again. I would like to pay cash instead in stores till my contract ends .
