I feel a little bit disappointed with thier service

"Dear blachta,

Hello!

We did a mistake, we didn't block the payment of the rig owner in time, so the rig owner got paid.
Could you contact him to arrange a refund please?
We are really sorry about that, this is an uncommon mistake we are not doing often!

Cheers,
Mux

Your Betarigs Team,"

Best customer service ever !
