ADT poor service!

Shocking service from ADT. A panic button was pushed and response was over 20 minutes, well after the medics had arrived. Worse than that, ADT were informed that we were moving offices (within the same business park!), technician came out to quote for the move on the 3rd April 2018, quote was signed on this day. NO contact or service since that date, today is the 1st May 2018. We have been at risk for a month with no follow up from ADT. I shall be cancelling the debit order immediately and cancelling the contract due to non delivery. I will not risk the business or personal and will find an alternative, reliable security company.
