l received my car on the day before lockdown but on my inspection noted a list of staff not completed in the car plus Engine faults advised them on email with no respond also went there after lockdown they said they will contact me, been sending emails with no respond they dont call to advise what is the hold up. the car is over due for service cant take it cause they will give me a long list of staff Re-new it should have fixed. I really regrat allowing my insurance to take my car there they dont have customer service. now am involving my insurance am done with them.
