Shocking Service from ADT

We requested that our panic buttons be moved from one business property to another on 23/01/2015. I sent through the move request on the 28th. The rep Mohau Mpiti was scheduled to come see me on 29th at 08:30. He arrived 2 hours late. We requested the original relocation plus some additions items. At this time I told him when the relocation needs to be done by. Unbeknown to me he dropped off the quotation at our offices whilst I was not in. He didnt bother to enquire who he left the quote with. Yesterday after not hearing anything, I contacted them to find out what is happening. I was told that the quotation was dropped off. I asked him to resend it to me and this morning he phoned me to speak to our cleaning lady to find out who he dropped the quote off with. I then requested that he email the quotation to me, which I received in the form of a photograph of a written quotation. I have been asking Head Office for his supervisor's details, which are being ignored. The quotation is not broken down properly for us and exceeds our move in 2013 by 700%. We now don't have access to the building we moved out of but ADT expects us to pay for the service.
