NS & I website - problem changing profile details !

Cavair001

Im now registered for my premium bonds but when logged in and go to Profile/Details there is no way to change phone number and address.
Their Help info says go to "Change" when viewing my details, BUT there is no CHANGE button to select !!!      Why is this not showing or is their Help FAQ wrong !! 
Chatline and Phone lines are so busy.  Any help appreciated !!

I have just checked and there is a change button alongside each of the following eight personal details:

Address
Phone number
Email address
Marketing preferences
Transactional text updates
Security questions
Password details
Tax details

I have checked and, like @RG2015, have the CHANGE buttons visible:

Thanks, but My profile and details page still doesnt show any Change button alongside these!   Will have to write to them as can never contact them by phone or Chat.

If you have just opened your account it may take a few days before the option to change your phone number and address becomes available.

Did you ever find out why this happened Cavair001?
I have the same problem. Have tried on android and laptop, no change buttons. 
Very frustrating.
