Lost access to O2 account

I have not been able to log in to my O2 account for a few days on the app or website . I enter my virginmedia.com email address but i get an error to say it is invalid. When i click forgot email address i get a text with the exact email address VM are saying is invalid. ???

I am about to go abroad and need to add data to my O2 mobile but cant access the account.. 

This really is awful service . Looking in this community it looks like VM /O2 have not tested this new merge of services at all. 

I have several mobile accounts which i now cant access. 

Chat has been no help , Phoning customer service has no idea why i cant access and raised a ticket from which i have heard nothing and my next stop is the local o2 shop where i will probably be fobbed off. 

VM/O2 please sort this , your about to lose a lot of customers.
