Vespa — Battery down

Address:

House no 13 A Asomi path Beltola Tiniali Guwahati

I had my vespa servicing in july where after that the lockdown occurred so i hardly went outside and also the next of my servicing the vespa was not self starting it need to kick then only. After some days it totally goes off the lights of the screen and its not starting. Due to its not starting anymore i can't come for the servicing. However the service charge is too much but the problem is still there. Could you please resolve this? Asap it's urgent i was waiting for the unlock.. Neither i can start nor i can go anywhere..
