Hi Aaadino, thank you for returning to the thread to let us know!
I am so sorry to hear you are still having issues accessing your My Virgin Media account! I will send you a PM to offer supporting getting your access resolved for the cable account (My VM).
I will also ask some additional questions regarding the mobile app access issue such as:
-Are you having an issue registering?
-Have you ever had access to the Mobile online account?
-If so, when did the access issue begin?
-Have you tried changing your password?
All the best.
Molly
