Are old, accumulated telecommunication bills owed by the deceased considered debts that must be paid on his behalf?

It is a mistake to think that utility bills are not debts that must be paid. The contract between the company and the customer obligates the latter to pay for the service, and "Muslims are bound by their conditions." It is not permissible to resort to deception to avoid paying these bills, because that is consuming people's wealth unjustly and failing to fulfill a trust. Heirs are not obligated to pay the deceased's debt except from his estate, but whoever voluntarily pays it will have a great reward. The bill amount can be ascertained by contacting the company.
