While we are unable to increase the quota on an application, you do have a couple of options:
1) If you wish to continue using Netlify, you can wait for the quota to reset when the new billing cycle starts
2) You can upgrade to an Algolia paid plan with the Crawler add-on. Our Crawler is now included all paid plans at no extra cost.
The free Netlify plan, doesn't include technical web support from the Support team.
