Adt a bunch of lies and promises

I am a excsisting client. From last week wednesday I have been phoning in to adt control room spoke to maryke. Today I phoned in spoke to Geraldine it's tuesday almost a week later. I have requested to signage boards for my home as they got damaged all the occasions they told me they would deliver. Up until now nothing at all. I've sent 2 emails no reply. We do not see adt patrolling our street at all. I've phoned in earlier again to ask them whats happening. Spoke to Mandla said he will see what he can do. Is this the way adt treats there clients. For a simple thing like to drop off signage boards I offered to put it up self and to collect. Please advise. Should I just terminate there services and move to another company that would look after there clients. I am really not impressed with all these lies as they said it would be sorted. Why pay for a company that you dnt even see although they across the road from us.
