billing me R6108 instead of R628!!!

Hi<br> <br> Last Month i had an issue with you guys charging me R349 instead of R329 for my cellphone contract ,after the hello peter comment it was eventually sorted out and i was credit.The guy said i must call back this month as my bill will be incorrect.I called in and the first idiot a women named Buhle did absolutely F#k all she just put me on hold for 30 mins and said i must call back.I called back got through to another lady who looked at my statement and said it is incorrect and she needs to log a query that will take up to 14 days to resolve.I refused and spoke to her Supervisor Lusanda who said this money has already been debited off my account yesterday morning and she will get someone to call me.I am still waiting!!! this is your guys mess up i expect it to be sorted out immediately!!!!!! this is 10 times the amount??? i need my money back in my account and a normal bill why is that so difficult!
