Abroad credit card defaulter Hi, i was working UAE for more than 5 years and i used credit card from one particular bank, due my medical emergency i returned to India and its become just 3 months for my recovery. the collection agency has contact my friends through Facebook , and started calling and harssing them who are not even involve in this matter, but they are making stories and calling their office landline and troubling them for all this, i even called them gave my contact but the used abusive language and said pay the amount or else they will keep harssing my friends and family. What are limits do collection agency have when it comes to collection terms (as they harass me and family and friends ) As i issued a security cheque in UAE and cheque bounce is a criminal case in UAE; Will they be able to issue any arrest warrant on me in india (collection agency also stated that they can arrest me here and send me back to dubai for my trials) Do i have right to report this to police and file a case on them Even though am requesting to consider my sistutaion they say that they will send rowdies to my house and trash me if i dont pay them what they ask. I need some one advice on this so that i can be strong and bold to them. Am ready to pay and am not hiding. i would like to know my rights with reagards to this collections. please provide me an answer RF
