****mers and robbing customers

On April 29 I made an online purchase for a R72.00 meal, paid with R50 voucher and R22 debit. The online system confirmed the payment however once processed R72.00 was debited from my account and voucher showed it was redeemed. I immediately sent an email to the customer service advising of this and request they only bank the correct amount R22.00 a week later I received a call from a consultant from their head office, he enquired if the credit was done, I confirmed not, he then acted surprised and further indicated he'll refer to the brand (Birch Acres) where I collected the food and I can expect a call from then. Since then nothing, I made a follow-up on the 29 May and to this day still no correspondence and no credit. Nando's is running a **** and pretending to be fixing problem while stalling.

Please ensure that only R22.00 is banked for this transaction.
