Business ProfileforGlen Burnie Transmission, Inc.

Back in august took my truck to glen Burnie transmission to fix and replace a rear differential. They told me 2 weeks to fix. Had my truck 6 weeks. Got my truck back and less then a month my rear differential blew out. Took it back to them to have them fix it again. Told me they replaced the rear differential coupling again witch had nothin to do with the original issue with the truck. So they never even repaired the original part. Originally said it was gonna be 2500/3000 to fix and only charged me 1700 for them taking so long. Now they said I gotta pay another 2500 for a new rear differential I said that's the original problem you was suppose to fix but never did. I have paper work from them witch states on it. Needs a new rear and will replace with a new remanufacture brand but never did. How do I go about having them fix the issue they was suppose to do in the first place. Do I need to find a lawyer. I'm new to this and have no clue what to do. I'm coming up on 10 weeks without being able to work cus of my truck being at there shop broke down As you can see in the paper I uploaded it says needs new rear differential and ok to replace rear differential and in the description it even says remove and install rear differential but they told me they changed the rear diff coupling witch has nothin to do why my rear differential was locked up
