CUSTOM TELECONNECT INC. CTI Did not disclose fees for there collect call service Las Vegas, Lubbock Nevada, Texas

In January I accepted a collect call from my brother.  When I got the call they did not disclose how much the call was.  I spent about a hour on the phone with my brother.  I checked a couple days later to see what the charge was it was $38 for a hour. 

I thought that was high for a hour.  I just received my bill and the charge is now $87 for a hour.  I called them and they said the fees are up to the phone carrier or some BS.  They know if they disclose their fees no one would pay.  Would you?  So now I'm trying to get my money back. 

I do not agree to the charges.  If anyone know what else I can do let me know.
