Hi @Jon_K
The number on the BT SIM stopped working completely two days ago.
However I was able to answer my own question and I found out how to escalate the problem. And it has now been resolved. The solution was simple, but I will post details here is case they help others.
1. I had been contacting EE using the online conversation option on the EE website. I think this puts you in contact with people in India. They were all very helpful but it appeared that the options available to them to assist customers with problems are limited. They were able only to send emails to relevant people in EE and tell me I would have to wait 48 or 72 hours for a reply. Hence my frustration and lack of confidence in EE.
2. This morning however I phoned 150 and spoke to someone in the UK. She then spoke to someone in the porting team. They were able to work out what had gone wrong, the matter was assigned to someone to resolve and flagged urgent. One hour later the problem was fixed and the number ported to my EE account.
3. The lesson is: If you have a problem, by all means use the online conversation service but if the problem is not immediately resolved by this means then you will much be better off calling 150.
