Solved🙁 Minecraft - No Premium Anymore

Hello,
My name Ajayan. I've got a new Minecraft account 24 days ago. One of my awesome friend gave me a MC Giftcode. So I went to Minecraft website & So I've purchased Minecraft. 24 days later yesterday evening about 20:00 I logged into Minecraft. I saw only ''Play Demo'' so I shocked!
I went to minecraft website & I've logged in & In once ''Im not premium anymore'' !?!?!... I never got minecraft without my friend. People says its only $20 but for me its big money! Im not rich person to buy games every time! all i've got cracked. Minecraft is my one game that i've bought but never without my friend. So... Can you guys tell me please what can I do for this? Is there any solutions to get my minecraft account back?
I hope you guys understand my situation!
Please

contact mojang,and if you want ill send you an account that works.

that must be a bug then , contact mojang and tell them that you bought a mc code and it revoked it during the 24 hour , they will ask you non sense questions but they will give you one, if they dont ill see if i have accounts for you

Your friend carded you a gift code, its highly illegal and it always gets revoked... Your friends a douchebag.
