Credit Card debt

I have an outstanding balance from my VISA credit card from my home country.
As i lost my job there for about 2 months and found a work here in the
middle east, i was still paying the minimum amount due in stated in the
bills, but for some time lost interest of paying due to financial crisis
hovering over my family\'s needs. Eventually, a legal letter came to my
parents house and sought for immediate settlement, as they were asking for a
huge amount (from 21k to 60k++) i replied via mail to them expressing my
willingness to pay but under installment terms.

I received no response from them. After 4 months another letter was sent to
my parents house coming from a different legal entity but for the same
cause. I told my mom to inform these legal firms to refrain from sending
letters to my parents\' house and email me instead. Again, there was no
response from the new firm but letters keep coming that my mother is already
worried.

Previously, they received a letter saying that my parents house is being
assessed in lieu of my outstanding debts. Is this possible? I know that no
debt is transferrable from one person to another unless implied by the
debtor. Please give me advice on this situation. Thank you.
