Pick 'n Pay and smartshopper

My husband and I went to Pick ‘n Pay Graandendal on Wednesday 25 November to buy our groceries and make use of all the black Friday and smart shopper deals. Our total came to R 6 438.94 but no deals was deducted or went through as the lady at the till (supervisor) said that smart shopper was offline and all the stores are having the same problem and that I should pay the full amount and that she, the supervisor will sort it out with smart shopper the following day. According to the supervisor smart shopper will locate the money that is owed to me on the smart shopper card. I said as long as I get my money back it will be ok and my debit card was swiped for the full amount of R 6 438.94. The Thursday I received a phone call from the supervisor to say that she emailed the till slip to smart shopper and asked me for some personal details she had to email. I phoned smart shopper on Friday 04 December and the agent gave me *** as a reference and said that I need to email a complaint with a list of all the deals that did not go through and a complaint, which I did the following day, the amount owed to me is R 625.16. No reply by Monday 07 December I phoned again and spoke to Sanelisiwe Zezi and was told that I have to wait 2 – 4 days. Today 09 December I phoned again and Anita Nkosi told me to email them the till slip and highlight everything that did not deduct/go through, this I did. I told Anita Nkosi that someone please need to phone me or even confirm on the email that my email was received but no luck. I phoned again and spoke to Pamela Khumalo and I was told again that the store need to send the till slip after I told her that I have already sent the till slip with all the highlighted line items that was not deducted or gone through, clearly the email have not been checked since Friday when I emailed a copy of a list that I had to make myself of all the line items that did not deduct/go through. It has been 3 weeks and I still did not receive my money back!!! Every time it is a 15 – 20 minute phone call which I have to pay!!! We buy our monthly groceries and everyday necessities from Pick 'n Pay.
