Bilkish Associates — harassment

I had a loan with SAMBA due to medical emergency I returned to home country with 6M leave, end of 6M as my recovery needed more time as it is chest pain the same had informed bank during the course. As I lost job I intimated my settlement of company to pay the bank. As jobless & running financial crisis carrying medical I couldn`t cover presently the dues. Bilkish came in picture started pushing us. I communicated the truth with medi reports and condition to hold till I recover to cover the due directly to bank. Today they visited my parent house and haressed my wife on phone and mailed notification to pay with in 24-48hrs / they will arrest via police and cess my passport at travel to any GCC.
Could any one help to handle the situation not to go worst and it is thrashing my family
