No inetnet on MTN data. No support. Unable to resolve. 5 months...!

Cannot get MTN to get my internet to work on their data. Have spoken to call center numerous time who "reset" their data. Have purchased new data bundles. Hva erest all my data settings on iphone 12 latest IOS, Have spoken to their technical data department twice. Can never speak tot he same person twice, so have to rexplain every time, and they do the same as the preveious person. The get to speak to someone is the workst IVR in history and when you do get to someone (try reporting *****, someone actually answeres) they put you on hold. Appalling service.
