Inner City Wonderboom - Bad Service

I took my vehicle to Inner City Wonderboom in order to have it FIXED. After inspection, I was informed that the Head Gasket blew. I asked them to proceed to have it fixed. After about a month, I received my car. However, it was not 100% fixed. I noticed an unfamil**** noise on the car and the car lost more than 1l oil in less than 1 week. I took the car back to have it sorted. Now, my car is with Inner City Wonderboom for about another month. Each time we follow up, they are full of excuses. I am of the opinion that they do not care about the customer's needs at all. VERY DISAPPOINTED WITH INNER CITY WONDERBOOM'S SERVICE (OR LACK THEREOF)!
