Overpromise and Under deliver

Booked in my vehicle for repairs on the 15th March 2021. The workshop manager provided an optimistic return date of 4 days as all the parts etc for my model are readily available and it seems minor pending further assessments and approvals but assured me of no delays. Low and behold we receive an update that my vehicle will only be ready late next week. Customer service is lacking and my disappointment is beyond measure. You're not doing me a favour, you're being remunerated for repairing my vehicle and holding me virtually hostage because you've already started the repairs. My insurance company will get my feedback and everyone in my circle of influence including family, friends, acquaintances and many clients will hear about your incompetance. Please take your time with my vehicle and try to do a decent job. Please don't rush because of this post.
