DENVER -- A mysterious fee shows up on your phone bill, but Qwest isn't the bad guy here.

A series of complaints to Call 7 For Help reveals a potential flaw at a national billing service and whoever pays the bills in your home might want to know about it.

Call 7 For Help has received three complaints from Colorado consumers who say they were billed by Zero Plus Dialing for calls they didn't accept.

The long distance calls in question originated at various payphones around the country and not a single one of the consumers who contacted us remembers getting the call in the first place.

Here's how you can tell if you've been billed by this company:

Your Qwest bill will itemize a charge to Zero Plus Dialing Inc., listed right under your new charges summary.

From what Call 7 For Help can tell, erroneous charges range from $13 to $15.

Remember, Qwest just prints the bill, Zero Plus Dialing is the one billing the fee.

Consumers who try to resolve this on their own can typically get partial refunds through their long distance carrier, but consumers who contacted Call 7 For Help got full refunds from Zero Plus Dialing.

If you want a full refund e-mail Call 7 For Help at Call7ForHelp@TheDenverChannel.com.

And we have an update tonight on a story Call 7 for Help brought out this summer. Runner Benjamin Gailey contacted us to complain that he didn't get his prize money after placing second in what was called the Jesus Run.

On Wednesday, Call 7 For Help received an e-mail from the founder of the race claiming he has declared bankruptcy. He says, "Jesus Run has no more funds ... and has ceased operations."
