The most important consideration is were you hurt? If not, then you can bring a claim to be reimbursed for the cost of the repair and any other damages to your car from this faulty repair job. Likely you can handle that on your own in small claims court. If however there were any physical injuries to you, then you should consult with an injury attorney.
