iTech - Please respect my wishes and STOP CALLING ME to sell me stuff!!

iTech refuses to understand that I will NEVER in my life make use of their service EVER again!!

I have been getting calls from them "to come and see me so they can talk to me about my phone system and printing solutions". I am not interested! I have had clients that made use of iTech in the past and most of them moved on to better service providers.

I have made it VERY clear that I do no plan on EVER doing any business with them again, still they keep phoning me, weekly.

In the past week I have had 5 calls from 3 different people at iTech trying to get me to commit on a meeting.

I have asked MANY times that they PLEASE stop calling me, but they just keep on phoning ...

Is there anywhere where I can report them ?? This is really getting out of hand!!!
