Nightmare customer service. Several Missed appointments and no response to letters and email. And now threatening letters saying their legal team will be involved for unpaid monies! What are we paying for exactly?!! ADT didn’t supply or fit our alarm. We have no contract with them - certainly haven’t signed anything. We inherited them from the company we used who fitted our alarm. I presume they bought out that company and now we are in this predicament of being involved with a company with dreadful customer service and total lack of customer focus. I shall be contacting our company solicitor about this harassment and speaking to the Citizens Advice Bureau.
