Carrosserie Euro Ltée

I got 3 more problems and Euro Volvo are all of em

Came in, spent 500$ for oil change, spark plugs and air filter. Left with an A/C that blows hot air and a high pitched noise everytime I hit a bump (AND a bump on my car by them pressing on it, trying to show me it was a shock, which was not.). They say it is bad luck.
