All emailed disappeared before 9/2

All of my email just disappeared older than 9/2.   I am using imap from several systems, but have been doing this for a very long time and have not had issues. 

I have checked different systems but can't find what might of deleted the. 

This may be unrelated, but there is nothing in the deleted folder after 6/2/2019. I don't delete much but not in over a year. Sounds suspicous. 

Finally if xfinity is monitoring this. I tried the chat and it was horrible. I tried to communicate with it and it just couldn't help me and put me in a loop. I asked for a human and it said yes, then asked me to specify the problem, back in the loop. Horrible implementation. You can't get rid of humans until you come up with a good AI.    And I couldn't find a phone number so this customer support interaction has bee really bad and maes me wonder what xfinity is thinking, and doubt my long term with xfinity.
