Billing and Address issues

Been a customer for a brave while now

Been having issues with billing since I moved house

Direct Debit fails and bills pile up and can't figure out why as my account says DB is set up

I did notice today that despite doing everything correctly at time of move - my package is still listing my old address and there's no way to change that

It SEEMS my new package is not connected to my current address and as such is not taking payments

I need help fixing this issue once and for all as the app is unusable - possibly due to this error
