I’ve adjusted my review downward from the initial three stars(A-OK), to one star(Eek, Methinks not), because of the owner’s comments about the initial review. Notwithstanding the«email cancellation is okay» language by the owner in his comment to the initial review, the actual contract the owner has every commercial business sign requires written notice of cancellation. Here are some examples from the service agreement: «Customer can only cancel or change this contract with a written notice.» «Customer must have proof of mailing(certified mail return receipt) or written confirmation on World Wide Window letterhead.» As I noted in the initial review, nowhere on the service agreement does the corporation’s address appear(which makes it hard to cancel, unless you’re planning on relying on the owner of the business to send«written confirmation on World Wide Window letterhead.») The family member who terminated their arrangement with World Wide Window Corporation did so because the service provider did not show up, as agreed, for a scheduled early morning window cleaning appointment before patients were scheduled to arrive. I’m sure that we can all agree there’s nothing worse than heading into work early(very early) for a service provider and not only they are a no-show, they don’t even call to let you know they’re not going to show up on time. And then the service provider is argumentative when you’re expressing your displeasure with the no-show. My family member was unhappy with the no-show. Yes, that’s true. However, the owner of this company appears to have customer relationship management issues. Best advice? Pick another service provider to clean your windows in the Greater Spokane area.
