No spares for phones

I bought a Dodge X20 from you in 2018. Less than 6months later the phone started giving me problems. I thought it was the battery and after alot of fighting i managed to source a new battery only to find out that it was not the battery but the flex/ screen. I have been all over trying to get someone to fix the phone yet nobody has spares for that phone. Where can i get my phone fixed? N a place where the phone won't be at the repairs for a month or two...
