Refund issue

I laybuyed a deep freezer at best home electronics at Bapong Keya Rona Complex on the 23 March 2022 on April I paid the outstanding amount and they informed me that they will deliver the freezer that same day to my surprise they didn't. 2 weeks later I went to the store to find out why wasn't my freezer delivered that's when I found out that it was discontinued and no one took their time to inform me about their issue, then I requested for a refund they asked for the receipts then I submitted only one receipt then I told them I misplaced the other one then they said I should do an avidaffit, I did it and submitted it. Yesterday I called them and asked them why haven't I received my money they said they've already dropped the money they can't refund me, I should wait for Monday or Tuesday, It's been 2 months since I have been waiting for my refund and on top of that the stuff have bad attitude
