Sorry, it's taken a little time to get back to you. I think you have just got confused about the benefits. You had 3 spins because you held level 1 (2500) for more than 180 days. Level 2 (5000) gives the same until you have held level 2 for 90 days when it will increase to 4.
You upgrade from one level to the next rather than stack them. ie. Level 2 does not equal level 1 + level 2.
Oh crap, I guess it's my bad then. I thought I will get 1 WoF added to the existing ones as soon as I buy more tokens.
No worries though. Thanks for the reply.
