Is it worth going through the process of filing a complaint with a debt collection agency that has my number for no known reason and keeps calling me? Or is it a waste of time?

A company called IC System has been calling me almost every day for weeks asking for someone with my last name. At first I just said no such person lived here. Then I got angry.

I think usually it was a person with the same first initial. However, this has been going on for a long time and that has not always been the case. Why my number? I have had the same phone number for well over 20 years.

I have stopped trying to reason with them, I just yell at them and hang up.

Today I looked up IC Systems on the web. It seems above-board enough [as collection agencies go, which is far below used car dealers or ambulance chasing lawyers]. They are on several better business bureaus and are a family-owned business. They even have a complaint department.

I decided to file a complaint but was advised that it would just be ignored and the calls would continue and any additional data I gave them when making the complaint would be sold to another collection agency.

There are plenty of gripes about them from those bothered by them. But some of this can be taken with a large grain of salt.

Opinions?
