Continious Haresment!!!!!

I'm disgusted with the continious treatening email and phone calls that I reveive from them. Having explained to them more than 6 times what the problem was with my ADT account and that it was a month to month account with no set contact period. I requested that they go back to their client and get the address of this paticular address because it was duplicated.......*********** and chasing money!!!!! Plus the cell number that they are using is my company;s new contract cell number.....
