Beware Vodacom are Rogues

Vodacom fibre accounts is the worst people to deal with. I sent through my application with a debit order date for the 1st of every month. They capture it as the 20th of every month. Call them to discuss the issue, they said they changed the date to the 1st of every month. Receive my bill and they charging me R100.88 extra every month still for the incorrect debit order date. Now they want I must pay them for their stupidity. I still have the copy of my contract which clearly shows the date.
