AAMCO Transmissions

After speaking by phone to the "manager" Erick of the 4701 S. Halsted, Chicago IL. 60609, location on Aug, 11 2021, I was directed to bring in the vehicle on Thursday Aug.12, 2021 at 8:00 am. I did, he didn't arrive till nearly 8:21, and walked right past me, no acknowledgement whatsoever. After which he acts as though I just wandered in from the street without an appointment. It is now 8 days later and no one answers my phone calls from said aamco store, what is going on at 4701 S. Halsted Street, Chicago, IL. [protected]? Rude and non professional at that location... How can I now trust that my car is been honestly serviced and me not being robbed by these guys?
