If you want to fight back you have to write a letter to the company contacting you advising them to only communicate via letter no phone calls.  If they violate the registered letter, you will then have legal recourse against the annoying company and individual.  That is the law.  You have rights too and they make it seem consumers have no rights except pass due consumer accounts.Now you know.

Ask to talk with me or my ex and I said no body was home and they ask when they come back on did not want to leave a message??

on appelle et on ne laisse pas de message ou bien on racroche

if they are really calling at all hours, you need to contact  the Office de la Protection des Consumateur,  because debt collectors are not legally allowed to harass you..

Il ne faut pas repondre.Do not reply

the polic can help us?
