Problem with App and Virgin Media staff lying to me about “closing” an account

I first tried to become a Virgin Media customer on 14th of December 2025 but the saleswoman on phone opened me an account with a Sim. I had not requested that as I have a contract phone with 02. I asked for broadband, tv and landline. Got broadband, tv and SIM. After hours of calls on 19th December, the account was “cancelled” I got compensation for her fraudulent nonsense. 
Went to 02 shop on December 20th and ordered the Virgin Media package I wanted and originally asked for.  I’ve had bills for SIM card account, which she had used a version of my name and a different email, similar to mine. Rang up. Said they would “close” original account( even though it’s supposed to be closed. 
It was installed yesterday. My problem now is I cannot access the App as it still contains details from original order. I was on phone to six people yesterday. The final guy said he has “closed” original account and it should be sorted today. It’s not. He also said I might have to use another email but I can’t do that either. I’ve uninstalled, reinstalled and it just shows old “closed” account details.
Can anyone help me
