app market not allowing me to login to my google account.

when going through market app i get asked to login to google account..i tried this very carefully but still error message that user name/ password not recognised, i created a new google account but same problem. i created 2 step verification but did not resolve, turned off 2 step verification still no joy. sometimes i get an error message saying that there is no authorised connection, virgin say it is all connected correctly. on google play i have no devices showing up at all. because of this i can't download onto the computer either. Is this an issue with google or the phone or both. During all this i do have a fine internet connection so it can't be that any ideas please i'm getting very frustrated.

all very bizarre so took battery out checked google account synced lo and behold app market there and no need to login hmmm so after an hour on the phone to virgin and all kinds of changes to accounts all is now good in my world. thank you for the reply though really appreciated virgin had given up. ; )
