Invalid pin. *I click on chat with costumer service. I chat with customer service online. They look up my information and respond with, "You bought the wrong card. Sorry for the inconvenience. You can not use that card. You will have to go buy another card."*I asked him to credit my account for the $** and I will pay the difference? *He said no.*I asked for his manager. *His manager said the same.*I asked for his manager.*He said his manager will call me within ** minutes.*I received a voicemail from a computer. *My phone never rang or notified me of the call.*I then call back the same * that left the voicemail.*I get another customer service agent. *She can not help me.*I ask to speak to her manager.*I speak to her manager.*He can not help me.*I am left SOL. I paid $** to straight talk to be informed I bought the wrong card.*He stated he was the highest ranked. No manager over him. *I stated he has someone who writes his check. *That would be his boss. *No one will refund or credit the $** paid to straight talk. *I want my $**.
