Not For Profit Licence suddenly disappeared and then deleted

Hi All

Have a big issue. Have a not for profit account for our charity. Renewed licence earlier in the year and all was ok and working. Then a few days ago I had reports of not being able to access data. After much hunting I found the below. Seems account was suddenly and without warning disabled and then reported as deleted a few days later. What do I do? I desperately need to recover the files that were on the associated teams? 

Any help would be much appreciated
