Google Ads Not Making Even Impressions Or Going On/off Randomly

I'm doing a search campaign for my independent financial advisor business.

Age >35 (also tried with no limits or >35 with unknown enabled)

Radious 20 Km around Rome (also tried 100 Km)

Segments: financial planning, investment services and bank services. (also tried without but they're set on observing anyway)

Schedule: Mon-Fri 06.00-00.00 (also tried 24/7)

Offering: conversions (also tried max click but nothing changes)

Budget: 50€/day. 10€ CPC/conversion cost (also tried with CPC/conversion cost 2€)

Announcement quality: Google says "excellent"

Keywords: [financial advisor], [independent financial advisor], [financial consulting], "name surname", "website" (i'm translating from my native language but you got it). Exact match on around 10 super related keywords.

I had some good calls/mails the first 1-2 days, then DIED. Some days i don't make even impressions. Others i do for half of the budget. 90% of the time i don't make even impressions.

Ideas?
