Incorrect billing

Dear Vodacom<br> <br> I took out a contract online for a HP laptop and modem for R350 per month. My account was debited with an amount of R1992 this morning. When I called customer service, Beauty the operator told me that your systems are down and she cant assist me.<br> <br> PLEASE contact me ASAP. You will for sure have to reimburse me or else I'lI have to take this matter further. This leaves a very bad taste in my mouth and I really want to cancel my contract.
