ADT SUCKS

I HAVE BEEN TRYING TO CONTACT ADT REGARDING ALL TYPES OF ISSUES, FAIL TO TEST SIGNALS, PROGRAMMING OF ALARM ZONES AND NOW CANCELLATION OF MY ACCOUNT. AFTER SENDING NUMEROUS EMAILS AND TELEPHONE CALLS - NO RESPONSE. THEN YESTERDAY I GET A SMS ASKING WHETHER I WOULD LIKE A QUOTATION FROM ADT (ALTHOUGH THE NUMBER USED IS THE ONE ON THEIR SYSTEM) I REPLY TO THIS SMS AND GET A PHONE CALL WITHING 4 HOURS!!!<br> SO THEY WANT NEW BUSINESSS BUT ARE NOT TAKING CARE OF THEIR CURRENT CLIENTS
