Theft

MTN refunded me 2 months ago for incorrect billing and usage charges so I was happy and settled then I cancelled my internet usage at the end of July and was told the billing runs from the 10th so I would be charged end August and I was charged over R1200 but told by September it would be correct. My normal charge is R449 but again this month I was charged R990.00!!!! I have called and told to wait as they can see something wrong but it takes 7-14 days.. I need my money and I want my money!!!!! As well I am tired of being told that I must restrict background data as I queried why my data is gone in 3 days... I have been happy for years but since May this year my gigs are flying and I am doing the same things I have been doing for years... I have been with company for years and always praised them but MTN is becoming a bunch of *******!!!!!
