BAD SERVICE BY EDGARDS FESTIVAL MALL

On the 15th of May 2023 i visited Edgars Festival Mall. I made the purchases by "pay just now" total amount of R1900. The 1st installment was R633 that went through from my side and I was told that the transaction failed from Edgars side.. The shop refused me to leave with the items and did not refund me the money. I was told i will receive the money on the next day from Pay Just Now. Until today the 21st i have not receive my money. No communication from Edgars Festival Mall. I don't know what is happening at all. Such a bad service. I want my money back
