Xpress Tires and Auto Repair

It's been like two months since I went there with my car for a check engine light, they charged me $220.00 just to check that out. They told me that certain sensor was sending wrong signals and they had to order online that sensor because at auto zone they don't sell it there . I'm still making phone calls without any news. By this time I'm tired of waiting I need my car get fix so I can take it to the smoke check.
