Although my experience with Signature Mazda isn't as severe, its still a negative one.
1) Back in 2018, I went with my wife to look for a Mazda 3 hatchback. Walked in, no one came and greeted us. We asked front desk for a salesperson to come, waited for 5-10mins, no one showed up. Out the door we left. Went to Freeway Mazda in Surrey instead and were greeted with much better customer service and happily got our car there.
2) fast forward to this year. We wanted to get a SUV this time and wanted to check out the CX-5. Since we were already in Richmond, might as well go in and see. Same thing. No one came to greet us. Off we went back to Freeway Mazda again. In the end, we got a CRV instead.
Maybe I should post my experiences with them on Google so they can threaten me with their BS law suite as well.
