Unsatisfactory service

I have upgrades online in July 2024 and up until today I had no feedback from Mtn. It show upgrade was successful but nothing absolutely nothing. Phoning them does not help they tell you it a mistake on their side and that they will escalate but nothing been thru that process twice, spoke to Thapiso yesterday and again heart and mouth promise to get this sorted This is the most ridiculous unworthy unsatisfactory way of handling a customer Just take note I have a contract with them since 2011
