Loose sr when it said victory in comp

so i was playing overwatch comp and i was doing really good
i suddenly disconnected and joined back almost 1 min after and it said victory. Later i go to my profile and checked my sr and lost like 40 srs. I don’t know why i lost srs. Please fix this problem for me and gain back my srs. please and thank you

Don’t disconnect and it won’t happen.
Nothing a discussion would change.
Accept it and find the reason for the disconnect.
Disconnects are unacceptable in comp.

Did you reconnect to the victory screen, or did you reconnect before your team won?
