What service? because there isn't any

I decided to make contact with Hisence myself. this is after the 3 weeks that I've been waiting for Game. I managed to get the bearing required from a spares shop but there are only certain parts they were able to assist me with. I still require the rubber seals which I was not able to find anywhere and all the repair places I've called said ill have to contact Hisense directly. Made my first call on Friday 28 Aug 2020 , The lady sent me a photo so we can be sure of the part, mailed her back and confirmed the part. Monday no call back I decided to call back - 5 persons later and not one is able to give me price and that they cant confirm that they have stock but they'll get back to me. The service center in Milneton phone just rings and nobody answers or just says it's busy. I get that the product is no longer in production but the product should still have spares somewhere. I get that it's lockdown and may not be as responsive but it shouldn't need to take this long just to get a simple answer. Yes we have stock, delivery cost etc etc.... and when you say I'll call back then call back even just to say I'm still waiting or looking
