UNEXPLAINED OVERPAYMENTS FOR JANUARY - WHY?

I am already so tired of having to go back and forth with your company.<br> <br> 1. On the 16/1 I got debited with an amount of R577.00 and to date no one can tell me what this amount is for. I get bounced around<br> <br> 2. On the 31/1 I got debited with an amount of R2115.75. I have three numbers on this contract of which the main contract *** was due for an upgrade. I changed my contract to a SMART M and was advised that there would be no additional cost to do this. To my dismay my bill was much higer than the previous month<br> <br> Please can someone at Vodacom advise urgently what is going on???? I want an urgent refund as this is not on. <br> <br> Ursula
