Squeaky Clean Windows

We orginally booked an eavestrough and outside window cleaning. 2 weeks before my appt I called to change it to inside/outside window cleaning and I didn't hear back. I called again 1 week prior to the appointment and finally heard back 2 business days before assigning me a time that didn't work. I called back and got a new time noon-5pm and they never showed. I missed work. I called and they said they would look into it and the next day, they called back at 830pm to say I had an appointment the following day noon-5pm. I called and told them I would book with someone else. Very disorganized. Too bad, their work was great last year.
