Well, I was expecting a reply after killing 2 cockroaches in F in April 2018.
The second one crawled across my table in front of the FP and ISM, who were apologizing for the first one (which I killed while I was cleaning the table before take off).
I didn't write an email / comment card but the ISM filed a report. She also gave me some service coupons.
Should I be expecting an email? CX obviously doesn't care and I have zero expectations...
