Edgars *********** accounts people

Just is COVID lockdown started I paid my Edgars Account in full as I knew I would not be earning, and I don't want any nasty bills. But in the last 3 months, I have been phoned continuously telling me that my account is now in arrears and I better pay up. When asking what I owe them money for I was told its "card fees" very high card fees indeed. I asked them to look into it and come back to me, still waiting, next call I was told its "Insurance" what insurance they will get back to me. the same story next call was its Club fees I know this was stopped when they stopped sending me magazines, so WHAT IS THE MONEY FOR why the continues callls and threats that my limit has now been brought down and that I better pay up because the interest is just growing. I am NOT at fault here.
