I needed help for brawl stars ranked…

I needed help for brawl stars ranked and I decided to order from Kingboost for the first time because it was cheap. My order took maybe 10 minutes to get started and I played with the pro player vaultedstubyz
It was surprising to me that it was an actual pro player because most companies “pros“ are just average players but my booster was top 100 global.
I played very badly but they were very patient with me and gave me advice on how to play better.
I can recommend that booster and company aswell.
Nothing to complain about probably will buy again
