So checked yesterday and today and the issue has been resolved. It looks like the app and website software detailed code structures and user interactions has been resolved. So no wanting to spoil the outcome but why did BT not contact me during my issue and tell me that if might take a month to resolve as the new site was being built? It's the lack of response from them that is frustrating and me wasting time online and lodging a complaint. We all have better things to do with our time.
No matter it's resolved and come November I will be moving to a new supplier that I have earmarked and get me away from this nightmare of a company.
