Really Reaaly bad service and workmanship

I recently took my Vehicle to Renew It Green stone for some minor repairs It was really minor My Vehicle ended up being there for repairs just over 4 weeks I can understand it if they are busy But on collection i was really not impressed with the poor workmanship and *** Quality control that is enforced 1stly the body work and PREP work is really not up to any standard at all 2ndly the Spray paint work was really not that great i sure my son could have done a better job and he is only 6 years old So this was all last year middle December After i requested reworks i have been getting the run around from the 8th of Jan Today is the 30th of Jan and still no response all i get is we are working on it but i have to ask for a Update weekly and i am Over it
