I also get calls just about every day, they never leave a message.

I visited the link posted above:

I then clicked on the "Chat", and asked to be removed. Done and done. Will follow up if for any reason they continue to call.

Hope this helps anyone else

Hey folks...I work at this company. I hate the fact people associate our number with something annoying. Let's try this for an approach. If you're getting calls from us, and want them to stop - call me. I'm a Director with Info-Tech and will work to fix your problem. I can remove you from the list immediately or I can let you talk to someone about who we are (your choice...I won't ask you to do one before the other). I encourage someone to try this out and post some feedback here for others to follow suit.

I am ignoring them, but they keep ringing! How on earth did they get my number!

I see all of these other posts have to do with business IT help, yet this number called my personal cell phone!!  i am certainly not in any need of IT help, as i do not have a business.  we'll see if they keep calling...they messed with the wrong person.

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.

Left angry voice mail.  Never said what company with nor phone # to call back.
