PAID MTN FOR DATA THAT I HAVE NOT RECEIVED, ALTHOUGH THE AMOUNT WAS DEDUCTED FROM MY BANK ACCOUNT

I have bought 10G data via the MTN app on Thursday 30 December 2021. It was from the bundles loaded under the tab "work from home". I have been using the app for months and always buy my extra data via the app, work from home. the amount was R249. I paid with my bank card. the amount was deducted from the bank account, but i still have not received the data. I started phoning the call centre on Thursday at 8:30am (data was bought shortly before 7). The consultant requested that i turn of my device while she reboot the line, and turn it on afer 15 minutes. NOTHING. phoned back, another consultant logged a query and asked me to check again in 2 hours. received an sms to say query closed, still no data. phoned back again - logged a query. received sms later to say query closed, still no data. drove to the nearest MTN shop to speak to someone in person. they were helpfull, but couldn't do anything. they are a franchise with excellent service, but they have to call the call centre exactly like i did and logged a query. STILL NO DATA. keep on receiving sms' that the query was resolved/closed, but still no data. The consultant at the shop emailed my proof of payment and a screenshot from my app to customer care and confirm that i've paid but was not credited with the data. NO RESPONSE. later that afternoon, i phoned the call centre myself again. was given another reference number - by this time i already had 6 different reference numbers of queries logged and closed. without being resolved. i were on the phone for 40 minutes. still no data. also, the consultant advised that they have now changed the Work from Home data that it is exactly the same as the educational data - only for use on zoom, skype. I do not use that. I asked why the app doesn't explain that or confirm the changes? and since when? he couldn't answer and rep**** that that is the way it is now. I requested then that they close query, as I do not want the 10G data only for those platforms and they should credit my MTN account with the amount of R249. he advised that they can't before the query is closed. they have closed my queries the whole day everytime without doing anything, but now they can't close this query and credit met with the amount that they took from my bank account? i emailed the detail to my consultant at the local shop to ask that he try and resolve the CREDIT issue, i don't want that data, and he's been trying to sort it out, but reported to me that customer care are also ignoring him - an employee of mtn - and they are not responding to any of his requests on my behalf. it is now Tuesday, 4 January - i've been struggling with this since last Thursday, with absolute no joy or progress or feedback from MTN. I want my funds credited to my account and i don't want DATA that they have changed without prior notice and that i can't use. very bad service. (not complaining about the local MNT shop though - their staff is very friendly and helpfull and apparently just as frustrated with the bigger picture!)
