Rabies shot day 3- Battambang or Siem Reap?

I have to get my day 3 rabies shot on the 29th and was wondering if there are any clinics/ hospitals that people would recommend or to steer clear of in Battambang?

I had my day 0 shot in Pnom Penh which was $100 overall($25 for the shot, $75 for the doctor), so I’m happy to pay in this range for good care as I have travel insurance.

If there are cheaper options, that would also be great!

My other option would be Siem Reap, but because we’re travelling from Koh Rong Sanloem, we wouldn’t arrive until at least 5pm.

Any recommendations, advice and thoughts are much appreciated, thank you 😊🙌
