Incorrect equipment installed, no explanations given

I'm very disappointed with the service we've received from ADT so far. I am a business owner and had a camera system and alarm system installed with ADT in Herm****. We wanted a camera system that would be accessible remotely so we can monitor the business while not physically on site. The person doing the quote, Mossie Mosterd, understood exactly what we wanted and even repeated to me "yes, you'll just phone them once saying you see what they're doing and it'll fix the problem". We were quoted for a 2TB hard disk, only a 1TB was installed. The system installed cannot be accessed remotely. We were given no explanation as to how the system works or how to set up new users or change codes and were told no manuals exist for ADT's products. We have phoned and e-mailed Mossie and ADT head office a number of times asking for followup. Mossie has simply stated that someone else does the remote systems and that he does not know about the hard disk. Someone from ADT arrived unannounced during a staff meeting supposedly to explain how to set up the codes, after we expressly said that we require an appointment as we as owners are not always at the business. Nobody else ever bothered to contact us in spite of e-mails on 13 Feb, 15 Feb, 16 Feb, and phone calls made on other days.

At this point we would like ADT to remove all their equipment and refund our deposit so that we can rather use a different provider. We will not pay the remainder of the installation fee because we feel that we were ********** and did not receive what we asked for or were quoted for. We've received nothing but excuses and lack of communication from ADT. We went with ADT thinking it's a big professional company but instead found the entire process cumbersome and confusing, and more like dealing with a startup.
