No IHD display and Bulb not reading daily usage

I had my meters fitted last year, July. And had issues with my IHD not connecting to my Gas. It never even registered I had gas.
Then one day it just broke. Tried for months to get a new one and keep being told with out a photo of it they cannot issue me a new one.

Also, mt Usage on my App does not work. I cannot and never been able to see my DAILY, WEEKLY or MONTHLY usage, only my yearly.

I have deleted the app, redownloaded it. Signed in & out. Does anyone know why??

Also, can I just buy a IHD of FB market place and link it up?
