Relative asking for my name insinuating I didn't take care of their pt hence why they expired

Idk sabi magrereklamo daw, diko naman alam saan siya magrereklamo since part yung hospital (since more on billing talaga kasi cash talaga ang problem) sa irereklamo niya. Baka ipatulfo ako lol idk but in my part, I did what I can do that's within my control and within hospital protocol.

Kayo po? May ganitong experience na din po ba kayo na hiningan ng pangalan para magreklamo? Natuloy naman po ba? Any advice on this?
