STI african king calling cards are a ripoff.  I purchased 4, a total of $20. and none of these cards work.  I purchased them at Duane Reade.  Consumers beware, these calling cards do not work.  When you contact their customer service, they place you on hold for a few minutes and return later giving you instructions to try your call again in 90 minutes.  They will tell you that technical support is working on it.  Do not purchase these cards.  It is a prank and their is no refund.  Once purchased you are stuck with non-working cards.  Their customer service number is 1888-320-0861.  Don't waste your money.
