ADT *****ing clients money

ADT’s aacounts department is useless. We have moved more than 2 months ago to a new house. I cancelled my account with the on more than one ocasion. And everymonth they still debit my account. I spoke to Sibosiso last week and he assiref me that everyting is cancelled. I even have. Letter statint this. And he promised me they wil pay back the money. Yesterday I went to pay money into my account for my insurance to go off. Gues what ADT debited my account again. So jo insurance for me this month. I sent the an email this morning before 6 am and demanded they pay me back. I dint have money for them to take as they please. I am still waiting for a response from them. How can they just take peoples money. And i have proof how many tomes i have emailed them that the contract should ve cancelled
