DONT HAVE AN CONTRACT WITH VODACOM

I have a few contracts with vodacom and i missed a payment last month with vodacom of R3200 which i made an arrangement and i paid before the set date of R3000. so by my calculations my account was only R200 in arrears which they were going to take off at the end of the month but no vodacom the another R3200 off my account leaving is at a total balance of R6200 that they have taken off my account.<br> <br> I reversed that amount.<br> <br> anyway everything goes off as it should besides for today. they have taken off another R2600 leaving me with no money in my account for the rest of the month
