What should I do first when a debt collector starts harassing me?

Short answer

First, do not panic and do not pay under threat — you cannot be jailed for a debt (1987 Constitution, Article III, Section 20). Then take four steps: (1) document everything — screenshot messages, save the call log with dates and times, and note anyone the collector contacted; (2) send a written cease-and-desist and demand an itemized Statement of Account; (3) know who regulates your creditor — the SEC for lending/financing apps, the BSP for banks and credit cards; and (4) file an administrative complaint with that regulator, plus the National Privacy Commission if your contacts or data were misused (RA 10173). All of these are free and need no lawyer. LabanPH assembles the evidence pack, the demand letter, and the complaints for you.

Frequently asked

Should I just block the collector?

Blocking can stop the noise, but preserve the evidence first — screenshots and call logs are what prove the harassment. Blocking does not erase the debt, and a written cease-and-desist creates a stronger record than a silent block.

Should I keep paying while I dispute the harassment?

The harassment complaint and the underlying debt are separate. You can report abusive collection and, in parallel, demand proof of what you owe (see /answer/can-i-demand-that-a-debt-collector-prove-what-i-owe) before paying a disputed amount. Never pay out of fear of arrest — that threat is unlawful.

Where do I file and does it cost anything?

File with the SEC (lending/financing apps) or the BSP (banks/credit cards), and the NPC for data misuse. All three are administrative complaints — no filing fee and no lawyer required. See /which-regulator to pick the right one.
