I think I'm going to join other campaign now because of higher rates.
So my question is can I take primedice signature and start using my new one now or do I have to wait till I get my payment from here?
Send him a pm with a screenshot of your signature in and tell him you're changing to another deal. I doubt he will withhold money from you and we can back you up if there's any issue. Stunna might raise the rates though, so it might be worth sticking around, but that's up to you.
Okay, good.
This is what I send him now: https://i.imgur.com/bXTRGqr.png
I hope everything will be good and I get my money
