CONTRACT WRONG!!!!

Hey Telkom seems like you and I are going to fight again like we did last year. I went and did a simple upgrade with your guys at Centurion mall absolutely NOTHING changed on my contract besides the amount I pay for the phone. I was supposed to pay R1000 and something but instead get an amount of R2400 odd rand. So I went and checked my statement and guess what you guys did, you charged me for a MIGRATION and you decided to take it upon yourself to load a data bundle of R600 odd rand. I did not request any data bundles be added also a migration would mean I came from another provider I DID AN UPGRADE! here is my Case number ***1.<br> You proceeded to debit me the R2400 odd this morning. I have put a stop order on it and ANY banking fees I occur from this you will be liable. I have fought with you guys before about billing issues and I am more than willing to do it again! Do not dare think about debiting my acc on the 15th unless its the correct amount otherwise it will keep bouncing. Also if you proceed to blacklist me for you mistake you will hear from my lawyer. I am not getting bad credit for you mess up! FIX IT!
