Edgars harassing customers for payment for no reason

I hardly make use of my Edgars account, but purchased an item two weeks ago when they had opened again. I was called today, Saturday afternoon 13th June,and asked how I was going to pay and when! I was not in arrears and never have been, yet why I am getting harassed? It makes me want to close the account. This is pathetic, and really annoying.
