Triple Account Billing

Hi<br> <br> I have a data contract with Vodacom and my monthly fixed instalment is 389-00. Today when I check my account online, I noticed that my bank account is going to be debited with 1235.45 end of Jan 2016.<br> <br> How possible is this?<br> <br> Please correct and advise once done otherwise I will have to move to another service provider.<br> <br> Regards
