Hi @isis2,
Thank you for your post and welcome back to our community forums. We're here to help.
I'm so sorry to hear that there appears to be a complication with a recent upgrade that was discussed. What are the messages that you're receiving about it? When did you last discuss this with the team, and what did they advise?
Regarding the O2 number/offer, have you spoke with O2 directly to resolve that? You can reach them by calling 0344 809 0202 (or 202 from an O2 handset).
Thanks,
