PayPower Blackhawk and the card is sold by Safeway Stranded my son 3000 miles away and then wouldn't answer their phones Internet

I went to my local Safeway, which I trust, and purchased a PayPower Visa Travel Card for my son.  He was traveling to DC and I was told by the tour director that a card was safer than cash.

After I bought the card I registered it on line.

Today my son called me and said that he tried the card and is unable to withdraw any cash.  I asked how much he had spent - he said "nothing"

SO I try to call the company "live agents" at 1:00 in the afternoon.  There is NO WAY to talk to a live agent.  There is no way to get any help.   

This is a shady company.   I called their parent company Blackhawk Networks.  Haven't received a call back yet.   I called the Safeway manager - he said they don't answer his calls either (which leads me to believe this is not the first time this has happened.)

DON'T BUY THIS CARD.   So mad.  I usually check reviews on line but the display was so big and part of the Safeway gift mall - I never assumed Safeway would sell such a horrible product.   

Really frustrating and scary.
