Hey Brelenor,

Welcome to the community and thanks for taking the time to post here on the forums. I’m sorry to hear of the issues that you’re having with your online account registration. I would be happy to take a further look into this for you but first I would need to confirm a few details via private message, please look out for my message and we can get started.
Kind Regards,

Tuning in

Hello Brelenor

Did you get resolution to your problem? As there are a LOT of people with this error code, could anyone give me an indication of the timeline for resolution of the problem and access to My Account? Am I looking at days, weeks or months for a resolution?

Hi there @ij66 

Thank you so much for your post and welcome back to the forums. 

I am so sorry that you are facing these issues, I can see that you are already in a PM with one of our forum staff. We do not have a specific SLA for this but the team will do all they can to help, please do pop back to PM where our agent will advise further. 

I had to ring up customer services and get them to log a ticket and somehow it got resolved (they just left me a voicemail saying try again) and then it worked. The response on this forum was useless, it took two days of back and forth and they couldn’t get past security checks, complete waste of time  

Thanks @Brelenor, I will wait in anticipation but won’t hold my breath 😉
