I called their toll free number and the receptionist accepted my requets to be taken off the call list. She said it takes about 24 hours to be removed.

I searched their number and found out they are a company called InfoTech. I used their online chat function to request that my name/number be removed from their list and I was assured that it would be taken care. We'll see...

Last week, this guy with a strong Indian accent called from this number and says his name is Joshua LOL. The first time he called he asked for one of people by name who works in the IT dept and that they had just talked to them the week before. I said "Wow, that's funny because she used to work in our HR last year." LOL.... He hung up.
He just called again a min ago. I asked him if he ever talked to anyone here and he said no, to which I replied "Ah, Joshua, you continue to amuse me. You called last week and hung up on me after I called you out on your lie." He laughed and said that he was not the one who called. I assured him that he was indeed the one who called, to which he then asked how I was so sure that it was him. I replied, "Because we have caller ID at our company" After a short silence, he promptly hung up again.
LOL. These people must think we are total morons. HAHAHAHA

Continues to call about every day on work line.  Never leaves message, but you can hear other telemarketers in background
