Approximately two months ago I found a charge on my online bank statement for $40.50 by mrslnet.com with this phone number. I did not purchase anything from this .com site. Like others reporting this, the phone number was always busy.
Then on April 13, 2009 I found another charge on my online bank statement which I did not make in the amount of $39.71, this time made by muhpop.com with a different phone number (888-205-2664). When I visited the website, instead of getting muhpop.com, I got billingservices.com. The phone number I dialed also answered as Billing Services Customer Service. It turned out that this company is handling both charges.
The representative of billingservices.com told me that they just process credit card billings for other businesses. I have no way of knowing whether that is true but it is quite a coincidence that they are handling two fraudulent charges against me. She also told me that one charge was for an adult web site but did not know what the other was for.
