Will I need to return every 30 days for COVID extensions at the Pattaya office, or will I receive a 60-day stamp on my next visit?

Regarding covid extensions on TR60 at Pattaya office:

I was given 30 days covid extension and told I would receive another 30-day extension without paying (1900 baht included both extensions).

Question: Will I have to return every 30 days in this manner. Or will I finally get a 60-day stamp on my next visit?

I have been in the country since last May 2021. I received 60 day covid extensions every time but not at this office. So far, Pattaya is the only office that required a return every 30 days.

Thank you.
