Bad customer service & Billing Account

I went to the store yesterday (02/05/2022) as my credit score it show the account is in arrears, but when they check on the system it shows nothing outstanding and they could not help further, how do i check what is outstanding as the people could not assist and i need to sort out this mess. i need a updated statement and it must be updated on my ITC. The stuff there are not even friendly at Greenstone Mall, instead of them calling the head office no one bothered to do so. they just gave us the number to call.
