Data file cancellation

Hi - I have just made a phone call to cancel one of my subscriptions - there were 6 in the cloud, and now should be 5 at the end of the month. 

The notice of cancellation email that I have received does not just refer to one company file and says "This is to confirm that your MYOB subscription has been cancelled......" - nowhere in the letter does it identify which file was cancelled.

I just want to be extremely clear that only one company file was to close (become read only at the end of this month) and the other 5 in the cloud are to remain active/live.

I don't want to go to do the next lot of bookwork only to find that my whole subscription has been closed as that would be a nightmare.

IF someone could please confirm in writing that only the one file was "cancelled" and the rest is fine, I will be much relieved. :) Thank you.
