Please do not post your email address in plain view like that.
Or do you want spammers and scammers to see it and email you lots of dodgy stuff?
If you have a problem then we would need to know more details to be able to offer advice.
However this is a user forum and as users we have no access to accounts or billing.
You seem to be saying that you have asked to change the email address that your existing licence is registered to?
Support do things like that all the time, people do change address.
They will want to know both your old and new email addresses, and your licence key.
As you already seem to have raised a support ticket please be paitent.
Your CCleaner licence will keep working, (until it expires), no matter what email address it is currently registered to.
Support is not an ‘instant’ service by any means, and it can take time (days, maybe a week or two) to get a reply from a support person.
