Excessive Billing.

We have too Top Accounts of approx. R350 times two?<br> We were billed R640 and again R740 last week, now Monday we were called and told to pay R640 again, how so! If it is a Top-Up how can we be billed so excessively.<br> I was at Voda city, tried to get a settlement on *** and ***, was given the run around, and then told to call a number?<br> Vodacom I will not ever do business with this company again once I have settled!
