Pick n Pay Accounts department not allocating payments

Pick n Pay store account paid on the 26th of November 2021 already. Sent proof of payment Friday the 3rd of December at 09H18am and today still not allocated. Call center says it can take 7 to 14 days to allocate. Why? The payment is in your account, the POP has been sent. I think this should be sent to the NCR for investigation. I work in accounts myself and never would it take 14 days to allocate a payment. Covid is getting blamed for everything this year, as I've been having constant issues with PnP and my store account. If this isn't allocated by tomorrow morning, I will be going to the NCR with all my complaints about this past year.
