Doggett Freightliner review: Repairs to cummins engine

They diagnosed problem to be a cracked cylinder head. They replaced it. Still have problem of fuel going to oil. Had old cylinder head tested at 3rd party cummins dealer and came back that it did not have a crack. Paid $15,300 for this and now they are asking for an additional $8,000 for new fuel pump. We feel that we should get our $15,300 refunded as they did not fix the problem.
