CHEATING OLD AGE PENSIONER OF THEIR WELL BEING AND MONEY

On the 01 of July I was doing groceries for my mother at Checkers at Lifestyle Center in Centurion and my mother's Post bank card declined twice and I ended up paying cash. An hour from that failed transaction I went to the ATM to check the balance on the card and it showed that the declined transaction actually went through and when I went back to checkers they told me it will probably go back to the post bank account after 24 hours which lapsed on the 05 of July and I took my frail mother to the post office to get the statement and the post bank statement shows that the declined transaction was a local merchant purchase. I went back to checkers on the same day and they have been giving me a run around and they are saying the transaction does not appear in their system and their head office has an IT problem they are trying to fix and they are blaming the delay to Covid19 because some of they stuff are working from home. My mother's burial society has not been paid, her medication has not been bought and according to me Checkers is deliberate and they are taking advantage of an elderly person.
