Vespa — My scooty stops and it doesn't start

I'm girl I have taken scooty for my college purpose but since from the day I bought it after month it started to stop and doesn't start it's very risky for me take it anywhere long distance because it stops I feel like I bought an old scooty not a new branded scooty I'm very disappointed with this scooty and service of vespa it's better to sell it than to use it
