im no lawyer or anything, but as far as I know, they cannot request issuance of warrant arrest just because you have unpaid debt with them. More so that PDC's are not involved. I for one was a victim of such harrasment just because my relative there was not paying my loan with them for 2 months. I work in the banking sector here in qatar and have worked for banks in the philippines as well, so I am pretty much aware of collection tactics. my advise, don't fall for this harrassing tactic, stand your ground and fight with them. don't let them degrade you and harrass you. equip yourself with the knowledge of basic laws and fight back. most of these collectors don't even know half of what they are talking about so the trick is to outsmart them. I took out a loan for 100k in a lending agency there and issued pdc's, and for 2 months, I was unaware that my relative was not depositing the payment until a collector messaged me on ym. He was claiming that I had bounced cheques and stuff, and that he will report me to my agency, blah blah blah. I stood my ground, asked for bounced cheques which he can't show coz there weren't any, I asked for my contract which they dont want to provide, to which I told him never to contact me anymore or I will sue them. these people wont really call you abroad and pay for overseas charges just to harrass you, so don't be afraid. unfortunately though, we don't have the law that limits interest rates anymore, so what I did, I hired a lawyer to negotiate with them and I just paid off the entire remaining balance less 75% of the interest. the 75% savings I got is what I paid my lawyer, I did that not to save money but to piss on the lending firm for harrassing me. lol
