WHEN DID WOOLWORTHS JOIN THE *********** & DISHONEST?

After paying the account BEFORE due date and far more than the amount due, I noticed with concern that the payments were not allocated to my account. I called and followed up with an email on 15/1/2021 sending proof of payments and request to allocate the payments to my account. 2nd Email send on the 18/01/2021 again with proof of payments attached and again a request to credit the account, to no avail. 3rd Email send on the 19/01/2021 this time to "accounts management services" & "***, Ms Najumunisha Karaan and Ms Sabatha. Once again to no avail, the amount of R8000.00 paid was now "missing" and not reflected on the account! In the meantime I am harrassed by Nationwide Recovery, by rude individuals operating as debt collectors. WHEN did Woolworths join the *********** and dishonest? After paying well in advance and far more than the amount due (R1100.00), I am now subject to harras*****t by foul mouthed aggressive debt collectors! EXPLAIN YOURSELF WOOLWORTHS.
