did anyone get a call from a 499 number with the message that 'you cannot use your card due to insufficient funds' which is crap because i have money. this was at 1PM EST. I checked my balance then and the website (mobile) worked and showed the correct balance. now, at 3AM EST the website is not working and based on previous reviews im very concerned that i have 'no money'! anyone else concerned about possible theft/hacking???
