Need more like you justis...a few years ago I had a failure with a garage roller door motor...it literally fell off as the door was winding up...lol It was a big garage door.
I googled and found some bloke that reckoned he specialised in garage doors and emergencies, being the door was stuck halfway, I called him and he said he would come right over.
He turned up a couple of hours later, nothing against Kiwi's, but he looked at the problem and said sorry he can't help me and left...the next day I got a bill for $180.00 for a service call.
Never paid it of course and emailed him a few facts of life...
