Poor PNP ASAP service

Good day. I have huge problem with Pick n Pay and their customer service. I ordered stuff on their app on 17 November. They deducted the same amount of money twice from my account. I sent them emails explaining what happened. I've had no response as to who's dealing with my quiry. No has called or emailed back to say they are working on my issue as I've already emailed a bank statement which indicated the money they took. I will really not recommend using their asap app for ordering groceries.
