charging to much for collect phone call.

I, made a collect phone call from a wal-mart pay phone because i could'nt get it to take my money,You'r company needs to let the caller know in advance how much it will cost. I only talked for a minute, but was charged for them taken so long to put the call through.If i had know the minute i got to talk i would have just drove home would have cheaper. I'm telling everyone i know make sure they don't use your servive it is a ripp off.  14.95 is to much to get to talk to the person for one minute. should't have to pay for someone for 9 minutes telling you they're putting your call through.
