BAD ONLINE SERVICE

I placed an online order on the 01.06.2023 and paid online. Order was finalised the same day. On the 04.06.2023, Sunday at 05:00 am in the morning, my bank account was debited again with the same amount. I logged a case with KFC on the 05.06.2023 and the matter has still not been finalised. They keep on telling me they are battling to trace the payment for the 05.06.2023.
