Pathetic customer service

I have noticed that this business does not respond to Hello Peter's complaints. I can only assume Mr. Willem Hanekom (Regional Manager) will not be replying to my complaint. On Saturday 16th October, my family and i had a light snack at M&B Canal Walk, upon paying the waitress, the card machine jammed the receipt, we told her not to bother with a receipt and handed her half payment in cash while the other half was from the card. It seems that when we left, the cash in the holder went missing and the waitress caught up to us at the entrance saying the money was missing. The shop could not provide ANY evidence at the time as to where the money had gone and insisted we pay AGAIN. Firstly they made us feel that it was our fault, Secondly, the restaurant did not take any responsibility for the waitress not keeping the cash with her, the reason why she insisted on leaving the cash on the table is beyond me, and knowing we did not need a receipt she stepped away to fix her machine and two knowing we were leaving. the next day the manager sent us a video of us at the table, yet again no evidence of what happened AFTER we left the table. This poor response has left me with a bad experience which will NEVER happen again at ANY Mugg and Bean as we will never be customers of your establishments again.
