I contacted them again today for an update, was informed the original lady dealing with my issue would have to get back to me. I found this strange as I understood my case had been escalated onto the tech team.
Anyhow, I'm awaiting contact from her now.
To be fair I'm already not impressed I'm tied into this o2 contract to get the benefits of my specific tv/broadband deal. I left o2 years ago thanks to less than competitive pricing combined with poor customer relations. First my extra sim being missed, now not being able to monitor my phone contract thanks to the my o2 app not registering is frustrating.
Price point for tv and broadband brought me over from sky (after 3 years). The broadband is quick with vm, no doubt about that...but I've honestly spent more time trying to rectify issues in my first week with vm than I did in 3 years with sky. I've already decided not to switch my wife's phone contract away from sky (that's what the second sim was for).
Fingers crossed the app issue is resolved soon.
