Baddest and most unacceptable service EVER

I took my car in for repairs on the 29th of June, i was told that it would be finished in 7 days. I called to check the status after the promised 7 days (7th of July) and i was told that the car is not yet done. I was then promised that the car will be done in the next 2 days (10th of July). On the 10th of July, i went to pick up the car as promised. The car was still not finished on the 10th. They took me to the workshop to see the car only to find that less 50% of the repairs were done. its been 2 weeks now, 2 full weeks and nothing was done. 2 full weeks and i still don't have a car.
