Overpriced and useless

Upon review of what I was paying for ADT, i firstly found that I was paying almost double what others were charging. After a call to them they were able to offer a rerate which they supposedly dropped but didn't.

I then found an even cheaper security company and so I tried to cancel. Firstly I was told that the people responsible for helping to cancel were not in the office as it was early January. I then followed up few days later and then was told they don't work after 4. By then, some cancellation deadline had been surpassed and was told i was liable for another month. Naturally irate about this but fine, take your money at the expense of losing a client. But they could not even get that right, they were billing me for the original amount and not the agreed upon rerate. There is a lack of compassion and understanding that the situation was different in the holidays and that by missing the cancellation date by one day they weren't able to accommodate me. I cancelled the debit order and now this company want their money and send me messages to contact them. Exactly 15 attempts to contact the unreachable Denzel Naidoo, which seems to have quite a history of being useless according to reviews, has resulted in me not knowing how to sort this out, so here we are writing a review for some sort of action. All which could have been avoided if actual humans, not robots worked at this company!
