Very bad customer service

Emailed for a quotation which was received very quickly. I then requested a site inspection to make sure if any additional materials or charges will be applicable and specially said that someone will only be available until 12. When no one pitched i called 12.30 and was told by the lady that she would share my details with the technician who would call me. After almost an hour of no one reaching out I called backed and she said Kyle the technician said he could only come between 6 and 7 that evening. I told her that this was not a very good start and that they confirmed the time with me 3 days prior at least someone could have notified me and keep me informed, I then told her that if they don't want the business I can go elsewhere and she then proceeds to tell me I'm welcome to do that its my choice.... the nerve... I don't think businesses know what their staff gets up to..... needless to say bo one ever came out. Sale lost for 2 installations.
