No aftersales service from Pnp

I purchased a defy top loader on 23 July 2021 at Pick n pay amanzimtoti. By the end of Jan 2022 a plastic part in the machine broke while the machine was in use.. I have been calling pnp a since Jan 2022, eventually on 28 Feb, Kereshnee advised that since its more than 7 days since the machine was purchased defy will not cover the part as they only cover the electrical anything plastic isnt covered. Service calls and repairs will be my cost. I disagreed and she gave me Afsar the defy reps number. He has not even read my message to date, now answered my calls. Lodged a complaint on defy website still no contact. Eventually called an after sales service number for defy and the technician advised me to go back to pnp and get an affidavit to make my case stronger. But my sales person at pnp no2 needs to work, defy cannot assist me. So it seems defy uses cheap plastic parts and then says oh we not responsible because its plastic. So who is responsible for a 6 month old machine that just broke. Never will i purchase a defy product again. Never will i purchase an appliance from pnp either Really ssad that 2 well kno2n household names mean nothing any longer.
