Upgrade problems

Dear Sir / madam,<br> I wish to complain about the wrong billing on my account.<br> <br> I am complaining because I have requested an upgrade of R149 BYO TOPUP MON-TO-MON to my previous R99 BYO. To resolve this problem I would like my contract to be billed with the right amount as requested.<br> <br> When I first learned of this problem, I contacted the Virgin Mobile customer service and one of the Champ told me that a R199 BYO was loaded instead into my account, something which I never requested in the first place. I then contacted the Virgin Mobile customer service again to get a resolution but every time none could do anything about the problem. I believe that this is unfair because I feel that Virgin Mobile has an obligation towards its value customers.<br> <br> I look forward to hearing from you as soon as possible to resolve this problem. I may be contacted at the above address and phone number.
