unwanted calls to my cell phone

For all of you out there that are having a problem like myself with getting these unwanted phone calls.  I did some searching and the calls are not coming from Digitcom, they are coming from Telephone Management.
I got an email address and a phone and fax number.  I found Digitcom to be very helpful to me with this matter. The man I spoke with said they were getting a record number or complaints about this company. When I called the phone number, someone answered, and just kept saying hello until an answering machine message took over.  That number is 866-225-1956.  The email is trey@telephonemanagement.com.  The fax number is 503-296-2500.  I intend to send them fax after fax for however long I can stand to do it, see how they like paying for paper and ink, like I have to pay for their stupid calls on my cell phone.  My faxes are unlimited, so I don't have to pay for them.  If you have free long distance service the same would go for you.  I also intend to give this idiot Trey a piece of mind in an email.
