MTN - ONLY WANT TO CHARGE YOU EXTRA

I am HIGHLY upset with the service I have received from MTN lately.

My upgrade date is stated to be September 2023. Usually and early upgrade would incur a cost of under R150. MTN keeps telling me that I need to pay and upfront fee of OVER R3000. This is ridiculous. I am further told that my "early upgrade" will only commence in October 2023. But the information I receive from the billing MTN app, states the 18 September 2023. I have now come to the point where I am actually fed up, and even trying to upgrade online is an issue. I keep putting in the OTP given to me by MTN, and the same MTN website is stating the OTP is incorrect. I am also done with the customer call centre because when I call in for upgrades, the automated response I receive is " speak to a service cham" but then I am not given the option to choose to speak to a service champion!

If MTN is going to be this worthless, I will be retracting ALLLLLLL my contracts from them, and I do not care that I have been a customer with them for over 20 years. I am honestly tired of this BS!!!!!!!!!
