he said he change adress for me so i can use my credit card to buy new plan and work on it right away

next day i try to but realised my username (email was changed) which is very strange I text with other guy and he said he will do it for me

then nothing happen till now and today i try to sign in my abode stock which is i am one of contributor

i cannot find my contributor that i already submit more than 1300 images and have some sell there

from now i have new accoutn that its siad first start submit photos... it's mean all my thing in here are gone?

i try to ask them from contact abode but they said they will find specialise person to talk to me then disconnected!

so What i suppose to do? now i dont have all program i need to use and my contributor account is disappeared too.

Thank you in advance if someone can suggest me what to do?
