Mtn is just plain USELESS

Hi<br> I laid a complaint previously about my 2 cell phone contracts that I have with mtn. one data line and one cell phone line. *** I migrated to a 2gig top up and 2gig night express, I never received any night express since April/May this year when the migration was done. Why not? Mtn just cant answer me... I upgraded the other line, to R169 NOKIA/ MICROSOFT LUMIA 640...50 min + 100sms's and 100mb data...RIGHT... SO WHAT HAPPENED WAS I WAS SUPPOSE TO RECEIVE 500 MB DATA FOR THE FIRST 3 MONTHS... DID I? AGAIN NO! WHY NOT? I WAS TOLD THAT ONLY IF I CHOSE THE 100 MIN PACKAGE I WOULD HAVE RECEIVED IT. BUT THE pamphlet THAT I still have clearly says 500mb for the first 3 months...and that's the package I took. I received 300mb instead, this month for the 2nd time. My data just flies even if I am not using my phone.<br> I am billed R227 instead of R169. Plus for the data line I have been paying R135.99 instead of the R99 that Leachima from the store in Grahamstown said to me I WOULD PAYING THAT AMOUNT. I spoke to Elani, Magareth and Heidi (FROM PE BRANCH) about this matter, but still they could not answer me. (I have emails to prove) <br> THIS IS THE SAME COMPLAINT STILL NO RESPONSE!!
