a message to this caller " someone is looking for you already" get ready

These people are driving me stark staring mad!  Yesterday they called my house 11 times!  They are trying to collect a debt which was paid two years ago (and I have the canceled cheque to prove it.)  They just say their records show the debt outstanding and that I have to send them a cheque.  they are arrogant and ignorant and more persistent than a wasp at a honey jar.

these a***s keep calling me.. they are calling me because someone gave my number by mistake. Anyway I told him politely to F** off.. maybe I will have to visit them in person.

They are Credit Collectors.. They have been hired by big corporations to collect the debt people owe. Like T.D Canada...Things of that matter..

Just got a call from them and they left a message but didnt ask for anyone or give there business name they just said if I dont rectify this matter they will take further action, so of course im not going to call them back and if I ever do answer the phone to them I can be just a intimidating as them

They keep calling my son's cell number and asking for "william". they also have nbeen told three times that they have a wrong number
