OK Now What Do I Do?

Sent in my 4a for the battery replacement option and just received the Google repair store notification. I was not expecting them to have any repairs as I thought my phone was in perfect condition other than the battery. It was working fine prior to me sending in but now they say the phone has a cost to repair of $270. They don't even tell me what exactly the problem is with it other than a phone call problem? Not going to accept their replacement at that amount but it would be nice to know what happened!
