Unsatisfactory Feedback and Service

I am currently experiencing extremely unsatisfactory service from Brooklyn Motorlab. I have been receiving sms updates regarding the progress on the repairs of my motor vehicle, as well as calls from the workshop manager, David. Unfortunately, the feedback is concerningly inconsistent as David would advise one thing, however, the sms feedback states something else. Notwithstanding numerous attempts to phone them I am unable to get hold of David as well. My vehicle's return has been long overdue. It is unfortunate that one needs to resort to a complaint to get feedback.
