Unhappy customer

In 2017 I paid off in full my WW credit card and instore card, IN 2019 I receive sms and calls telling me I owe WW for a in store card and was handed over. I made contact with WFS CC so many times to advise them I do not have any card of WW, yet they still continued to hound me and then listed me. I made contact with Transunion who investigated and told me they saw WW . They would investigate. In May 2019 I received a letter stating that WW had been removed from credit status. In 2020 I re app**** for a WW CC as was going on leave, but due to COVID 19 had to postpone to April 2021. I requested a minimal increase, consultant confirmed that I qualified. I then get a call from WFS to say SORRY and referred back to 2019, meaning nothing had been corrected or was the consultant inefficient?. I had met all the criteria I have sent 5 e-mails to WFS CC and have had no response .
