Lived here nearly 6 years. Always had same window cleaner. All good. Couple of months ago was looking out of DD bedroom window and there looked to be a mark on the corner if the sill outside. ( Typically the but I couldn't reach. Mentioned to WC next time he came. He doesn't use ladders, he uses smart water and the long stretch ( hose?) to clean windows. Long story short. The mark wouldn't budge. Last month, he didn't clean the sill of the front bedroom. I asked if he could perhaps return and do this after he had finished next door but one. He then said words to the effect of, " you always seem to have a problem with me, I think we best leave it from now on". I was taken aback tbh I paid him ( online as I do) and haven't seen or heard from him since. Has he sacked / removed me from his customers now? I'm still not sure whatwhy this happened.
