Cancelled Account, still being billed

I cancelled my ADT on the 5th of May 2014 Via email. The mail was sent to a ADT email account supp**** by the local branch. I received a mail that they had received my mail & even spoke to the local branch manager confirming my cancellation. I then stopped my debit order but ADT kept billing me. I spoke to the local office multiple times & every time was told it would be rectified. <br> <br> ADT has now handed my account over to Debtsource who is even more useless than they are. I have sent my ADT correspondence to Debtsource over 5 times now & am told that they did not receive anything. When they finally confirmed receipt, I was told last week Thursday that they have sent the correspondence to ADT & I should have an answer by yesterday, the 19th of May 2015. Today I received another sms from Debtsource requesting funds to be paid into their account. <br> <br> When I called Debtsource now, they told me that they are still awaiting a response from ADT. <br> <br> This is totally unacceptable. Even when the consumer tries to sort out their mess, they just don't get back to the consumer. No wonder they were sued & lost.
