Buyer offered and I accepted. After that he requested for warranty period, I declined explaining that the unit might be damaged during his transport or his usage. Buyer is concerned that unit might not be a working one. I understand & proposed a whatsapp video of switching the unit on. He turned down flatly & insist on warranty period of 5 days. I declined again & asked him to re-propose a win-win way as what we need to do is just to ensure unit is a working during handover. But buyer went MIA.
