Its a correctional phone Service

They've left 5 messages claiming I owe them money for calls from a correctional facility in Oklahoma. I know that they're trying to scam me, because I only ever payed for PREPAID calls from my incarcerated friend. There wasn't even ever the option to talk now/pay later, LoL! I smell a rat!

Caller ID shows:

Lyle Failes
3816 Ancient Oak Dr Apt 1208
Euless, Texas 76040

for number 972-734-1111

I just arrived to US, I'm from Chile and just received this call from the number asking me to pay a bill.... I never used they services... What can I do in this case?

They call twice a day with bogus claims.
