How long should I give Virgin It to get back to me

About 10 days ago rang up customer services about an issue on hubby’s account. We have been unable to get into it for several months.
They tried everything to no avail and said they would upscale it to IT dept to provide a link sent to his email address so we could reset password. Nothing as yet so have had to use my remaining miles to book a flight late next year.
Should we ring them up again or give them a few more weeks.
