Gepps Cross Exhaust

Hi guys my wrx had a timing belt change done at gepps cross exhaust 8,000km ago which apparently had a warranty of 5,000km for workmanship but a 12 month warranty on parts and my crank seal (which is part of the process of a timing belt change) has either broken or come out leaking oil all over my car and these guys don't want to no about it. I think their service to customers stinks and I will NEVER take any car to them or recommend them to any one hopefully this post warns any future customers and take your car to a real mechanic business who actually care for their customers and take their work seriously
