Trying to sort out a broken phone on a contract for a deceased person, as well as the contract itself

Trying to sort out a broken phone on a contract for a deceased person, as well as the contract itself. It has been an absolute nightmare. Multiple visits to multiple stores, supp**** all requested documentation, been told consultants would get back to us. Useless black hole. Will never use MTN again. They have turned an already distressing devastating period of our life into a nightmare.
