so, you already facebook sync your old account and tried to login using facebook in new decive but it does not work?

you might be:

- mistakenly use a wrong account on facebook (my friend does, so it's just one possibility)

- keep on pushing on zynga by saying that you wish to transfer your old account by providing your customer number

- recheck your old account from old device to check if your old account is still available (if the account is corrupted, that means extra work and not sure if zynga can fix it)

there should be another way, but this much is what I know, I never have a problem with facebook login myself, hope your problem will be fixed soon
