Disgusting service vw alberton

Those people don't even deserve a star, disgusting service.. I took my car there 2 weeks ago for them to change my car battery, guess what my car has problems now.. my wipers are not working, my car doesn't start, my car radio required pass word and there's EPC sign now out of no where.. I took it back again last week Thursday, my car spend the whole day there for what exactly coz now its even worse .. my car is no longer starting now I have to get a mechanic to try help.. I'm never going back there again.. guys don't even do ur service there they don't know what they are doing
