Transaction Issue

I tried purchasing the CS:GO lifetime cheat and paid through PayPal. I don't have my bank info set on my account so I paid as guest but it tells me my credit card isn't able to be used at this time and to use a different credit card. Pay Pal told me to call the people I'm buying from and help me with this so now I'm here.. And I'd really like to use this cheat because of all the insanely good reviews its got and how many cool features it has.

Thanks.
