Sorry if i didn't explain properly that you thought i used automatic translation, it's true i'm not a native English speaker, i'll do my best to try and explain better.

My main problem is related to spins bought using reward points, there's an expired spin preventing me from rolling, i contacted the support multiple times to remove it from the system with no success.

Here's what i mean :
• When i go to WOF page you'll see that i have 206 spins (not sure why they're called free spins, i spent reward points to get them :p) :

• When i click play all, nothing happens, all i see is an empty rewards table :

• If i refresh the page and click play one, i get redirected to that expired spin, and my spin count becomes 0 :

• If i refresh the page again i can see the 206 spins again.

Currently, it's useless for me to keep buying spins using RP as long as that expired spin is still present in the system.
I can roll newsletter free spins with no problem.
