Bad Attitude and Terrrible Service

I went in on the 28/09/2015 to have my rims that were fixed by Gerald's put on, with new tyres & exhaust. I collected my bakie that afternoon but when I got home realised the front tyre was flat & seemed to have a bubble in it. I took the tyre back this morning 29/09 & was told by the owner Gerald that is is my problem because I should have checked when I left that everything was in order & I damaged the tyre by driving it flat. Then Gerald changed his story & said that the guy who fixed my rim was in fact in jail now for stealing so it was his fault the rim wasn't fixed properly. Bottom Line, i took my rims to be fixed by Gerald's Wheel and Tyre - they are responsible for the work that is done. The owner refuses to fix the damaged rim & replace the brand new tyre i just paid for. I paid to have rims fixed & new tyres put on, now due to their negligence have to pay again to have the rim properly fixed and for a new tyre. Gerald the owner was swearing at me and threatening me, that is no way to treat a paying customer really (Gerald's wheels&amp
