I had a new wheelchair delivered just before going on holiday. Despite explaining that it would need the wheels altering due to me being a double amputee it arrived without it being done. The man who delivered it whinged about it should have been done in the workshop etc and obviously didn't like doing what he was asked to do. There was no time to take it back and do at the workshop because of the imminent holiday. As we prepared to leave my wife asked me to lock off the wheelchair, yet despite doing it, the wheelchair continued to move. We discovered he had moved the wheels but not the brakes, which were now well away from the tyres. That's just downright dangerous! It's a good job there was someone at the house who was mechanically minded and could move the brakes for us. We also found the arms had been put on the wrong way round, too. I phoned the office the day after I got back (two weeks ago) and asked to speak to a manager/supervisor about a serious complaint and was assured they would phone me back. So, I have phoned again today and threatened to take it higher up the food chain. We are all human and make mistakes, but that kind could end up with someone seriously injured.
