Worse business to deal with

Car service city .... mall @carnival worse customer service ever...last year I went to service my car it had a knock inside the gear box....they managed to fix it but ....it few bolts missing from the box I went back , to let know so that they can fix their mistake....too bad they didn't bother to look at my car ....they dismissed my case just like nothing happened.....my 35 000 just went to the drain 😑
