Absolutely pathetic service. MTN are actually *****ing from their own clients!!!

Got a call on the 28th August, to upgrade to a better package for R269.00 a month. The call was recorded. I got the pro rate, at an additional amount of R150.00. Bearing in mind my cellphone contract was R149 per month. I upgraded to a 200 minute package with a 100 booster minutes (no one can explain how this is loaded or works), together with 2 GIGS data day and night. I get an account this month for R828.00, no idea how MTN got to this. I logged a call with billing, and will see if MTN comes back to me. Pathetic service from their side, but the debit order will go off on the 22nd, and i must just be happy with that
