Cannot access account

I have recently signed up to Virgin Media and need to gain access to my account.  The problem being that I can't because complete any details because it advises to call, which I can't get through to an actual agent to resolve this.  As far as I can tell, we're up to the set memorable word stage of the account creation.  I'd appreciate some assistance in resolving this, so I can complete the account set up, reset my password.

As a side point, in no way an issue for the agent who picks this up to deal with, I'm trying to upgrade to a more expensive package, giving your company more money, and am instead spending my Sunday afternoon looping options on the phone to no positive result.  I've previously worked for O2, I get it reduce customer service load as much as possible by using bots to resolve issues, but to be honest, if not for the fact Virgin is the only good provider around me, I'd have already cancelled.  Please help me resolve this.
