********** purchases on Edgars account

Phoned the Edgars Call Centre on Friday 14 Jan 2022, being upset that after 25 years, they are charging interest on a small amount. I wanted to close my account. Lady put me through to their Accounts Department. Consultant said they will rectify my account and that I should not close it. Two working days later, Edgars own ********** Department phoned me to say that R8000 ********** purchases have been made on my card, which means someone from Edgars stole money from my account. That is also my exact credit limit. My card is in my purse so no way anyone else could purchase on my account. Up to today, problem not yet solved. They said it will be investigated and it takes 21 working days. Today is 21 days and nothing yet being done.
