Took my car in to have two tires patched. Paid 30 bucks.Within hours, both tires were flat again, and an independent mechanic verified that both had been marked to be patched, but neither were actually patched. He fixed Big O's mistakes.I went in to Big O. to get my money back and was told by owner, Phil Martinez, that I had: "Hit something on (my) way home." I told him I had not. I had driven to my office and parked my car w/o incident. The AAA roadside assistant who changed my tires twice that day verifies this. There was no extra damage to my tires. The only difference was that they had both been marked to be patched (though never patched).Owner, Phil Martinez, called me a liar, the mechanic a liar, and the AAA assistant a liar, and then he told me to: "Get the hell out of (his) shop."I was actually kind of scared, so I did just that.
