Customer service lacking

We booked a move with this company and have been querying items on the agreement stated. We have had to follow up several times and the tone of the reply was actually a no-care approach. Then ONLY to receive a call from a manager, Caleb demanding payment in total even though we paid 50% as per the agreement. ON confronting him he became very unprofessional. I requested to speak to a supervisor only to be told he was the supervisor. I then asked to speak to the owner only to be told I am not allowed to speak to the owner at all. I tried to tell the "manager" that is seemed to be very unprofessional only to be shot down. Good start to client relationships
