Double deduction

Good day This morning I received a notification from my bank that an amount of R1099.00 was deducted from my bank account for Vodacom. Please advise on this as the invoice that I received was for R617.50 I phoned the call centre and was advised that I was double billed. This is extremely irritating to me. This is the first month that I am with Vodacom after forcibly being moved from Autopage and already my account is a mess. Way to go Vodacom. KINDLY REFUND ME ASAP SO THAT MY REMAINING DEBIT ORDERS CAN INDEED GO THROUGH. IN FUTURE, PLEASE ENSURE THAT THE AMOUNT TO BE DEDUCTED IS CORRECT BEFORE DOING THE DEDUCTION. PS, A FUALT ON YOUR SYSTEM IS NOT AN EXCUSE FOR PUTTING YOUR CUSTOMERS IN A DIFFUCLT POSITION SUCH AS THIS. Numbers in question: *** *** HC Jacobs
