Firestone in Irving tx Firestone's special Irving Texas

We are filing with the attorney general  firestone is a rip off my son has his car looked at by three mechanics  I wanted to help him ,.I asked him to meet me at mall in Irving and I would help him,.the biggest estimate we got was 120 lowest 80 it has rained for a few days in Texas so the cars were all muddy Jeremy drove to meet me at the mall we had lunch while Firestone looked at his car the called with an estimate of 800 and said things  were wrong that resently were replaced by him since he works on cars he just was busy and I wanted to help him and teach him to trust others,, when he got thevestimate with all the things that were new he felt they were ripping him off he got upset and asked them to just give his car back ,,the manager told them to give him the special and proceeded to drop his car he ran back in the back as they roughly lowered it scratching it on both sides like clamps.the scratches were fresh huge scratches it was obvious it just happened. When my son got mad and called the cops the guy called them too ,the cop and him were evidently friends and told Jeremy there isn't anything he could do but leave,,,he was so made he got arrested feeling violated and abused,, FIRESTONE is the biggest RIPOFF ever, I asked the cops to please please look at the scratches and he need up hand cuffing me ,, this was a sad day
