We have been getting telephone calls from this company for YEARS. We have asked each caller to please stop calling, and inform them that they do in fact have the wrong telephone number. They apologize, inform us that our number will be removed, and then moments later another representative calls demanding to speak to the same person.

Today we informed the caller that they had the wrong number and once again as that our number be removed from their system, they agreed. Two hours later they call back, we hang up on them, they call again, we got on the line with their "Supervisor" "Max Endrew" (Original name Huh') and he stated that he would remove our information from their system and if there are any problems to call him directly at 315-299-3466.

I don't have much faith in what he had to say, as this has been going on for the past 4-5 years. (On and off, but mostly on) This is harassment and something needs to be done!

Doesn't do any good if you don't get the name of the company.  Try to get it next time, and even better get an address if possible.  
One way I have done it is when they ask for a person say just a moment, set the phone down and never come back to it.  It's there dime your wasting.  I agree in the bottom line they are all scum, especially if they don't care enough to put their name on the caller ID or at least leave a message.
