<prompt> Human: I got a 50 dollar gift card the other day from my uncle to help pay my cell phone bill since he didnt want to use his card. Well. So far with this 50 dollar Visa Gift Card I have paid my 47 dollar cell phone bill, and bought items on two separate days with each receipt saying my ending balance after purchases is 50.00. Now when I tried using my card to pay for something over the phone, they said it was declined due to an invalid CVV. Tried calling the issuer of the prepaid card, their automated system sent me to support after putting in the CVV that was on my card and having it be the one not on records. They just told me I must be reading the numbers wrong. I also asked what my balance was and pending charges didnt tell then I used it already and they said 50.00...what could cause this and should I stop using it for legality?  <response>: Its the gift that keeps on giving!
