I usually don't post much as you can see, however I need some advise or comments if I handled this situaton OK. This new customer call and wants his gutters cleaned, no problem go the same day clean them out by hand, too wet to blow, about a 30 min. job. I just sent him a bill for the service and instead of payment he sends a note saying I did not clean the gutters they were still full. He had to hire someone else who coincidentally came later the same day. He said he got up on the roof and saw they were still full. I am totally blown away by this, because I know for fact I cleaned them out. If I sent a worker maybe I would have some doubts but not in this case. So I called him up and he just kept saying the same thing over and over how they were not cleaned out at all. Finally realizing that I would not get anywhere with this I just said forget the charge its onlt $40.00 not a big hit for me. I still fell like I have been cheated not to mention being accused of being dishonest. What could I have done differently?
