I wonder if I chose the right place to complain.But I do not have other way to sovle the problem.If I am wrong.Please forgive me .
    Several month ago,I created my Yobit account.After that time I transfer some BTC to the platform and buy some coin.
    For satey I set a google authenticator.For a long time ,everything is OK.But about 20 days ago.I just can not login my account.The renson is that  evey time I want to login, I put the GA code from my telephone,the platform said is invalid,then it said the platform send a code to my email.But I checked everywhere just find nothing.This happened more than 30times.
  What confused me is that：Firstly,I try to change my password,uesed  the same GA code from my telephnoe, the platform accept,and succssful changed the paaword,so it prove that my GA code had nothing wrong.Secondly,evertime I try to login,Yobit send me two emails with the same detail just to tell me login from a  new address,without the GA code.That prove I can get the email send from Yobit.So I do not know why I can not find the GA code they said theg had send to me .
  I tryed email Yobit for more than 5 times.They just tell me to check my email everytime the same answer.I am tired,just want to get my BTC back.
So please help me.
