Very angry and service has become unprofessional

I'm livered with the new teljoy product that needed to be delivered today to us wasted our whole day waiting and when I called Teljoy customer service all they stated was it's dispatch problem. No assistance no care and no service. My husband is ill and not well and from tomorrow we are not available at anytime and the rest of the week which I did send messages and emails stating that the delivery must be before tomorrow, I'm very angry and we must sit here the whole day not even receive a call or even help from customer service. Very unprofessional and not at all service what we expected.
