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

I have received a call today from this number on my company cell phone.
I do not give this company number out to anyone.  So, I am unsure how they received my phone number.

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

These guys have been calling me twice a day "with an important message" . This is an automated message. They ask for Hernandez Rodriguez and say "if you are that person, press any key for an important mesasage". If you press a key, out of kindness to tell them you are not him, you are told to "hold for an operator". What a stupid way to do business. They eat up my cell time while I wait, because there is no option to tell them I'm not Mr. Rodriguez. If you hang up they keep calling back. I finally tracked them down to Global Credit & Collection Inc.,in Markam, Ontario. After three tries (2 hang-ups) I finally got throught o them and the receptionist said they would delete the number. HOWEVER, this same things happended a year ago and they asked for the same person then. After doing the same dance for a few weeks, I was told the same thing. They seem to have resurrected the file and the harrassment.

Its summer and holy, do they persist! I like to sleep in because I'm a teen and they called like every hour yesterday! I wanted to figure out who these guys were, so I picked it up today and clicked 1.
They asked for my dad but I'm like, "he's not available and I'm his son, I'm talking because my parents don't have good English." They wanted to verify some information which I kind of gave in a I don't know tone lol. They asked when we came to Brampton and I said, "we moved here about 7-8 years ago," and the guy goes "oh, might not be you." Next, he asks for my postal code, and last question was my dad's birthday. This last question, I answered "err.. March 25th." He asked for the year and I'm like "1950ish..." and he's like, "sorry, this isn't the person, sorry, have a good day," and I hung up.
So, that brings me here. -__-

they call every morning afternoon and evening - does anyone know who they are?
