lies of the used car salesman

On purchasing a vehicle from auto pedigree, odeon promised to repair any faults and bodywork needed to be done , on the 24th of last month the car was dropped off and on the 27th at 17:30 the car was picked up, but only 1 fault was looked at and the breaks which was one of the biggest faults was not done. The manager Oswin just said is sorry his sales person did not follow up with the workshop. The car was dropped off this morning and he refuses to give a courtesy car and the car will be given back on Friday, hopefully it will be completed. This is now 8 days that the car will not be in use and he refuses to see that these four days are because they messed up in the first place , and all he can offer is an apology, because he head office will not allow him to give a courtesy car. I guess courtesy is not part of the deal at auto pedigree
