Absolutely disgruntled client!

I made a payment for my credit card on the 29th of March 2022 and it was a card payment till today that payment has not yet shown on my account. How does a store lose track of a payment of that amount. Is there no one reconciling the payments at all? I have spoken to at least 3 consultants today at head office, i emailed the receipt to queries email address; I spoke to the manager at the wonder-park store to assist and now I have to personally come into the store. This is very bad service and I am absolutely appalled that no one can assist especially because it is a payment of R7000.00
