Seeking Google Ads Expertise for Finance Client in India

Hey everyone! I've been running Google ads for a client in the finance sector in India. We're facing an issue with the ads, and I've tried consulting with many but haven't found a solution. If you have any Google Ads experience, please DM me; it would be helpful. I'm also trying to set up GTM, but if I fail with Google's ads, I won't be able to pitch GTM.
