Hi, I spent months in contact with EE often on a daily basis, over this issue, it eventually come together and I could see all my accounts, who they managed to fix mine and yet not fix others is baffling. Like you every time I spoke to someone they said they would pass it to the technical team (or the not very technical team)
At one point I was told to delete my account and re-install it, but you can't do that as every time I picks up your old account.
I spoke to staff in an EE shop, they seemed to think it was an easy fix, the fix they told me was to get EE to delete my account and re-install it, as above that can't be done.
A lot of these problem have been caused in my opinion by BT pushing every one onto EE, and the problem has been EE can't migrate your BT account into your EE account. I don't understand what's going on with the BT brand, why have dumped the broadband and mobile all to EE, sadly to an inferior service and product.
Also I have found the EE router is not as good as the BT one, in my case the wifi strength is not as strong and I struggle to get a signal to parts of the house where it was ok before.
I hope you get your billing sorted out, all you can do is keep on at them, I contacted BT head office regarding these billing issues whether that helped I'm not sure.
