Melany,
It's not a question of whom to trust. It's more a question of there is alot of things going on in the background and NO ONE can or are able to give you a definitive answer.
Just a couple of months ago crew at LGW were told that there would be no more direct entry recruitment into LHR and right after that they recruited 154 direct into LHR. Crew on temp contracts were told that it would be a temp contract only and then they were given permanent contract at LGW.
At the end of the day people, recruitment, crew, wannabees can tell you what they want, you can believe what you want but until it's in writing in black and white it's not certain (and even then things can change)
As so many of our managers like too say you'll just have to wait and see.
