worst customer service received

I took my car in on 07/02/2020 and only got the first update on 17/02/2020 and that was only because i started calling in and asking questions. I have been assigned a service agent she does not answer my calls or What's app messages.I track my car through their website and it has been at the same stage for a week and a half. A little courtesy call would have been appreciated just to let me know if there are any delays so that I can be at ease.I will never recommend these people and hope not to having dealings with them in the future.Hopefully my car returns this week.
