My phone number still associated with a business account closed in 2017

[EMOG]

I had a business O2 account which I closed in 2017 and transferred the number to a pay monthly account with Virgin mobile. 

No issues until Virgin mobile moved to O2 and I tried to get My O2 to work, basically I  gave up but due to emails received from O2 about changes i thought i would look again and by following some advice here i have got it to work but on a different mail address. 

The thing is I  can still log onto my old business account which still has my name, address last billing date etc and email address and I  am assuming that this is why I  cannot get My O2 to work on my preferred email which worked fine for Virgin mobile.

How can i get the old account info from 2017 deleted.
