Poor service and bad attitude

I bought a dash cam on Friday, 09.09.2021. When I got home, it was not working. It showed on screen that there is no memory card, and then smoke came out from the charge unit going into the lighter. When I called them today 06.09.2021, Obert Taruvinga (which was the sales person who sold it to us as well), informed me that there will be no exchange. The purchase slip clearly states: "No Cash Refunds. Exchange only or Store Credit". He did not even offer me a chance to speak to the owners.
