Woolworths changes account numbers

Woolworths changes account numbers without notifying the clients and when payments are not received on the new number they list you on ITC. The reference number that I used was the same reference number that I have been using for the last 4 years. The reference number is exactly the same as the one on my account statement. I do not know why Woolworths went and changed the account number. No one is your office can give an explanation. Please note that all future payments will be made in account ***09 0032 as it appears on my monthly statements. There is still an amount of R200 made on 4/9/2020 that does not show on my statement and I still get call from Woolworths everyday accusing me of not paying my account. When I call Woolworths Customer Services they inform me that my account number does not exist on their system. Regards
