Pathetic service regarding closing of accounts

I am running out of words regarding the pathetic service I have received from Woolworths store and credit card departments. My store account and credit card was settled in November 2018 but up until today I am struggling to get these accounts closed. Even though I have settlement and closure letters Woolworths continue to send the credit bureaus incorrect info every month stating my accounts are in arrears. Numerous calls and emails and yet they can’t get the accounts closed off. Pathetic pathetic service.
