Experts in Auto Body Repair

After spending almost 1k getting my car's body repaired and re-painted, I was expecting a crack free body for at least a year. Unfortunately, not even a month, I am seeing a few cracks! They really did not do a good job in welding the cracks and rusted part on my car. If I were to go to the experts in the field of auto body repair, I doubt I will have any heartache now.
