ADT Secure Drives poor service.

I'm forced to give one star. I contacted Adt Secure Drive for a tracking device for a vehicle. All "paperwork" and debit order were done via the phone with promises for installation. From there my experience with these people became nightmare as at the first installation date came, the technician "booked sick". For a few days, nothing, nadda from them until I phoned again. Was given another date, but again a no show or call. I phoned again, and again had to hear excuses of "technician sick". They then went quite again and on 24 Feb 25, i phoned again to be told they can instal only on.04 March 25. I then said no, i will rather cancel this deal and the lady then said she will come back to me. They can do installation on 2 March 25. This all after 7 calls from my side alone. This is a concern how customer was treated as what will happen if they're really needed. Hopefully some Manager will act and correct this technical departments poor services!
