have you uninstalled the MYBT app then re-installed the MYBT app as there has been numerous updates since you previously posted.
This is using a web browser. I've tried in multiple, still showing as inactive after nearly 8 weeks now.
Unfortunately you are going to have to speak to a human i think,it's probably a account problem at their end,Good luck.
Don't blame you it normally takes hours to bat aside the incorrect advise before you end up speaking to someone who understands the problem and can help.
I've had this and the worst nightmare was attempting to get help from BT. It was caused, and has been several times, because BT put an order in for Digital Voice. Every time they do this it blocks full access to my account. One can still get messaging/chat, but the rest is locked. It took me 4 hours to get some semblance of help and to get the reps o understand the problem. Most I spoke to kept laughing! BT really have lost the plot and they've now made it impossible for certain consumers to get help. especially the elderly, hard of hearing and those with "unusual" illness's. If one enters a complaint, nothing is done. Instead an email is received stating "we have your complaint" Then another arrives later to tell us to contact them again if the complaint is on going. Even if contacting them again, we are ignored then a third e mail arrives, "we've closed your complaint" Closed yet no apology or action. Something is drastically wrong at BT. The worst thing BT ever did was to drop the complaint section on their website and to drop email contact. It's now impossible to speak or contact anyone in management.. They also tell us to contact them via "snail Mail" if we need to complain. So much for 21stcentury technology. It's a disgrace and they need to change their policies.
