Sales Team Ineffective

Monday (13/04) I called requesting that I would like someone to give me a quotation for Armed response at my new home. I received the following reference number: ***. The message also indicated that Shavir Singh would be at my home on the 14/04 at 17:00. I rushed home from work, however Shavir never arrived. I tried calling Shavir twice. He chose to ignore my calls and never responded to my voicemail message either. I then called your contact centre at about 17:30 making mention of this. The lady advised that the call would be escalated accordingly. It's 15:25 now (15/04/2015), and no one from ADT has given me a call. I had CHUBB Security, at my previous home, and clearly ADT doesn't want my business, so maybe it was a fault on my side to terminate my CHUBB contract because at least CHUBB responds.
