Payment enquiries - pathetic customer service

In August 2015 we received an email from ADT informing us of the implementation of an excessive response charge policy. We exceeded the maximum threshold of 5 responses in August, and were charged an additional amount in line with the new ADT Policy in September. No problem with that.<br> But ever since we have been charged this extra amount - in October and November even though we have not used the ADT response service since August 15th.<br> I sent two emails to ADT to ask for explanations. They are receiving my emails, as I get an acknwoledgement, but no one has had the curtesy to reply to them and to provide the required explanations.<br> ADT were a lot more reactive when they were trying to sell their services to me. Now that they've got a debit order in place, they just don't care anymore.... Pathetic Customer service!
