I called them and some one switched the line to its "service person" who helped me make an appointment. But when I arrived they said they didn't receive any call from me (even though I called them for three time in that morning due to the signal issue), and they didn't use the number shown on its website. However, the information they told me (like the price for mechanic check and their closing time) was exactly the same from what I got with the call. So who did I speak to? Terrible experience.
