Vodacom doesn't honour chosen debit dates

Vodacom offer an awesome voucher service through Vodapay. The Vouche Advance is a great idea, BUT when people use advance service, then Vodacom's service is lacking.

You get to choose a data to repay the advance. 2 days before the due date, you get a reminder. However, they then try and debit your account 1 day AFTER the reminder, and 1 day BEFORE the chosen repayment date.

This is not acceptable, why would you allow people to chose a repayment date, and then you do not honour it and just choose your own date instead?

I had an advance, to be repaid on 16 October. I got my reminder SMS on the 14th, reminding me it was due in TWO days, then today (the 15th) they attempted a debit.

I transfer money into a specific account to use for this service, in time for my chosen repayment date, and each time you try to take it early, I lose money in bank charges.

Vodacom, you MUST do better!!
