Delay in Authorizing Car Service - No Responses

I am really not satisfied with the service I have received today with regards to my vehicle service claim.

BMW Northcliff sent an email at 10:22 subject "SERVPL/***" with a quote for service of my BMW. This email got no response - again at 13:23 they resent the quote and only got a response at 14:05 asking for a picture of odormeter reading.

The time is 17:03 and the workshop still has not received any approval communication! I have no car at this point while I wait for you to get more efficient in doing your work and this is not acceptable!

I will now take to social media to share my experience with your company!

PLEASE DO NOT TAKE ANY POLICY WITH THEM!
