Thankful for receiving free $2 in credit the other day but the credit only lasted 24 hours.
Could you please provide me your invite code so I can take a look at your account?
Here is my invite code SV84BK
I have verified your account and can see that the credits were valid for 2 days.
The expiration time will depend on the promotion rules in which the credits were acquired.
Hope you have a great day!
