I can't play on premium servers because the account I bought is cracked

Hello dear Mojang team! On Friday, July 11th, I bought a mojang account for minecraft with paysafecard. I played on it for 2 days and after one day it was cracked ?! I don't understand how it works, I can't play on it on premium servers and I've checked everything. Can you fix it, edit it or something, I would like to play minecraft again I hope you help me further. I don't want to lose my accou t like that. I'm so sad at the moment and will be sadder if you don't object, I mean me I used 25 payesafcrade, downloaded skins, BAC and so on. Please, I want to go back. I will be very grateful to you
