UV4x4 Poor service

Just letting everyone know about the worst service I have ever experienced. It all started when I went to UV 4x4(Brendale in Brisbane) to get a bullbar 2"lift and long range fuel tank for my r51 Pathy. All was good except the tank was expected to take a couple of weeks....no probs. After a couple of weeks I rang to check eta. I was given a date some weeks away. On the supposed arrival date I rang again and was given the old "I'll look into it and ring you back". No return call. So I emailed LRA the supplier who informed me there had been no order placed. UV 4x4 finally rang back and blamed the supplier instead of owning up to their mistake. Still I was willing to give them an opportunity to retain a customer by giving me a pair of spotlights and or airbags. They decided to pass on that opportunity by saying "we don't do discounts". I said I'll come in to get my deposit back. They said they'll send a cheque to which I replied "no I'll come in and get the money. They said that would be a problem as they can only authorise $500 refund. Not good enough, they are happy to take any amount. They have had $1200 of mine for the past 6 to 8 weeks but don't seem to care about customers!
