told off after asking for refund

I have been dealing with them for years. I overpaid and asked for a refund. Carol said I should buy something with the money. I said I would not because I am not happy with the service she has been giving. She asked for my boss and I told her I was the boss. She told me \no wonder the other business had taken my business"and that I was useless. <br> I told her that it was my money and I still wanted it back. """
