Didn't get the $6.99 kit that I paid for

Hi,

I was prompted by a kit at the main dashboard for a kit with ricochet M1 and viking M1 for $6.99

I clicked buy and went to the payment page. I paid the $6.99 and it showed that an error occurred but it posted the transaction to my credit card. So, I thought logging off and logging in would get me the tank that I paid for but it wasn't there.

Can any of you please look into it?

Regards
