MTN manages one thing best - to disappoint !

Absolutely pathetic service ! Both from (data) user perspective and Customer care : yesterday purchased a top up of 1.5G, 3 days, 500M a day .. This morning - no data, I need to recharge .. Minimal usage yesterday. The MTN app is telling me that I have used 1000,28M yesterday, day one of the bundle. OK, where are the remaining over 500M ?? Went to Cresta MTN shop, they referred me to 135, called then and 3rd time around I speak to a human (which is a great victory in itself!) and .. this is where things got really south .. The message that I still have 500M from MTN POV does not get through - I am told that I need to cancel out of bundle rates ! Then I am told that application do things on my kampiutaaa and I need to stop them. Wait, this is a good call, but if I accept it, then I want to see usage of 1536 M this morning, and investigate what ate my bandwidth, but all on deaf years .. MTN is going backwards big time, and we are in 2024, and I now have to move elsewhere, where it will be very likely the same but at a different and higher price
