My son has been using a prepaid calling card from this co; and it has the phone number on back with the code also. To my surprise it has just showed up on my phone bill for the first use he made 7/31/08. The company on the bill is called Coinjock and I am being charged .08 per min after he has bought the card. I will be getting many more; higher bills here soon. I can’t find out anything about this co; it’s like there not there unless you want to buy a useless card that will run up your phone bill. All I have is there phone no. and still can’t find out anything - 1-800-832-8875; can some one tell me any thing about them; and how to report them.
