I had a customer who was trouble from the word go. The day after the second clean she phoned me and demanded that I go round because I hadn't cleaned any of the windows and there were finger prints and smears everywhere. The language she used on the phone was of a seriously threatening nature, so I told her I would be straight round to have a look and rectify any problems with my work.
I went there and apologized for the problems, and asked if she would show me the offending windows. She simply said all of them. It's a fair sized house, and I thought the only way out of this was to clean them all again.
As soon as I started she got in her car and drove off. I re-cleaned all the windows and went home, expecting a phone call later. Nothing....
... Until a few weeks ago when her son asked me to give him a price to clean them. I duly gave him the price, which he tried to haggle. I told him that I wouldn't touch them for less. He then said I hadn't cleaned them last time, but I had been paid. I reminded him that I had cleaned them twice. He then said I had damaged some of them, and threatened to call the police. I told him I wouldn't try to stop him, before getting in my van and driving off. I had already binned them after the last performance.
I was polite as I could be (I was livid) and realized that this was just another example that all you can do is be as reasonable as possible, but you can't necessarily expect the same from some people.
If I genuinely caused damage, I would expect to pay, but not when the accusation is patently false.#
