Thank you for responding. The service falls way beyond what is expected. The very fact I cannot talk or email directly is a headache. As I already mentioned, I responded to the email claiming all transactions had been reinstated, but got a response saying I had no open tickets. 

I do find it patronising suggesting I check I have the right version of the app. I've also logged in online. Years of transactions are missing.

Nothing has been reinstated. I have even logged in and out again.

I find it hard to understand that there is not automatically a back up that customers can revert to when they need or download whenever they choose. It's a very basic function.

Of course, if this isn't resolved by QB I'll be moving to Sage software. Way more reliable.
