Dubai face it cs go servers help



I want to subscribe for Middle east cs go hub, so I can play matches in the servers. I don’t have credit card or any card whatsoever so I chosed the phone payment method. But for some reason I Can’t press “pay now” button whenever I put my number. It says the chosen method cannot be used for specified amount or something similar, I tried all the amounts still the same outcome…
Please I beg you help, my mental condition is unstable due to mm and it literally made me go to therapist. I feel so much pain and itch inside my head I literally cannot play.
