Verification of WeChat Account

hope all is well. My account was not active for almost two years and now I want to get the content of one of we chat groups that I was in.

I tried to login they asked me for verification. I put my mobile and send me SMS and it went fine. They asked me to get friends' help which I could not.

Would like to get help reactivating my account so I can get the content in we chat group.

How long does it take you? how much? what do you need?
