Avoid at all costs. Can i give this no stars? I rarely write reviews, but ADT have been so bad that I've actually started seeking out places to had to warn others. I've not received such terrible service from any company, let alone a security company, for a very long time. They give you conflicting info on the phone and via email. We had multiple false alarms (8 in 3 months!) which they told us they could do nothing about. My keyholders came to our property on several of these occasions and no one from ADT ever so much as emailed to check on it. They have no helpline outside of hours. They lie (they actually claimed the thing had never been false alarming, despite us having telephone records to prove otherwise!) Despite multiple false alarms and one of the sensors being removed (!) they didn't contact us once and were completely oblivious. Says alot for the level of security theyre offering. They attempted to raise their direct debit from £30 to £48 one year with no explanation or service change. They continued to charge the direct debit despite cancellation and told me it would take two weeks to refund due to a technical error - can you imagine what they would be like in a real security situation!?
