WOOLWORTHS DISAPPOINT!

I have had a Woolworths Store card for a number of years and use it often. In March 2023 I received an SMS advising that if I spent a certain amount in their Food store I would be rewarded with a "cash back" of R150 which would be credited to my account. This did not happen and on 15/04/2023 I sent an email to their finance department querying this. They asked that I send a screenshot of this message which I did on 05 /05/2023. I have had to follow this u a number of times as I was not receiving any information. Eventually I did receive a reply which basically told me that there had been a number of SMS messages offering "discounts" on items. I do not recall receiving these and if they are not on my phone it is because I was not going to utilise them. They still have not provided a satisfactory answer as to why my account was not credited with the R150 referred to in the SMS in March. I get the feeling that they are trying to sidestep my query by telling me about "all the offers which have been sent via SMS". Really disappointed as I have always felt that Woolworths are run in a professional and client oriented fashion.
