Extermley Bad Service

I bought My car 2011, before it can reach 3000 KM it started making lights, they could not fix it. Now it started to have no power, when I took it to Midrand after they fixed power, they swapped my water pump. Immediately the water started leaking. I took it to Westvall Jacaranda and now I must pay R8000 for new water pump. I Will never buy any car that is GM. it has been horrible experience
