I started my SaaS 3 months ago and Indian businesses are absuing the free trial

I have a b2b product which solves certain problems for marketers.It's called LocalAds

We have been growing organically on Instagram and getting 100s of signups everyday.

But, very few businesses actually want to pay for the product - they will use it for free, get good results but they will not pay.

Infact they log in from a fake account and use our trial plan.

1 dude made 19 trial accounts in a single day.

When we started identifying and blocking these trial accounts the free trial users got mad and started saying "i would have bought if you would have allowed me to make more fake accounts"

None of our international users have given us this problem and happily paid month after month.

Would love to know what should i do to grow this?
