Double billing

On the 07/03/2018 at Tygervalley Centre I purchased 3 items for R234.99 TAX invoice number: *** . I was assisted by Ursula Muller, the cash purchase was done on the mobile POS and it went offline after I entered my pin code. The transaction was redone and I asked if the transaction won't go twice and Ursula went to the manager and she confirmed that it won't. I left the store, after 15 minutes I received two messages with two payments that went off.

I contacted the store and spoke to Micheala who said that she will investigate, took my contact details and confirmed that she will get back to me. I waited the whole afternoon and noone contacted me. I had to call them back and she requested the numbers of my card and said she will call me today 08/03/2018.

I have been waiting for feedback and no one from the store contacted me. This is unacceptable because now MrP is keeping my money and no feedback is provided. Money doesn't grow on trees and I need to use my money ASAP.
