Pathetic service and ill treatment by service provider

I am very much disappointed in the pathetic bad service and incompetence from the staff members and manager @ Diepkloof square zone 1 Foof *****s Market. namely the manager (who should be brought to book and her position reconsidered) Ms Ria Sallo and 2 deputies : Ms Nokuthula Lubisi and Ms Tania Nkosi. I went to shop @ their grocery store on the 25/06/2021 and paid for my goods via debit card. The cashier said the payment declined. I confirmed to her that my bank had sent me a notification that the payment went through. Her manager was called on the spot. I also showed her the sms notification from my bank and even went as far as showing her my balance after. They both insisted that it did not go through and that I should return the goods or swipe again.

Following their instructions I swiped again and the payment went through. When I got home I noticed 2 transactions for the same goods had gone through. went to my bank and got my bank statement which reflected their 2 successful transactions. I took the statement to their shop and asked for a REFUND. They declined and said I should sort the matter out with my bank. I then went to my bank the next day and they confirmed that Food *****s should refund. Went bank today and informed them of the outcome with the hope of getting my refund but was told that there was no manager in the entire store and therefore no one can assist.

I am disappointed in their service and will be taking the matter up with the relevant departments as their HEAD OFFICE is too busy to take my calls after numerous attempts to contact them.
