Paid for expidited shipping on May 5th and still no part. They say USPS doesn't do exlidited however that is WHO THEY USE yet charge for a service they know won't happen!!!! Won't help us get the part, won't offer any resolution, nothing except just wait for the part. Never mind we have a vehicle down. Won't return messages nothing. After doing more research I have read MANY complaints about the same thing. They lost us a customer and out account for the auto shop. I want honest businesses to work with not scammers.
