Not trying to assist us in any way

Good day, My dear mom passed away the end of September, I have been trying to sort everything out. She took out a contract years back for my brother. He has been paying her to pay for the contract. Her death was a shock and we still are trying to get over it. They have blocked his number and unless he pays almost R8000.00 for all her contracts he cant port his number, get it on prepaid or take over that contract. He has his own business and are losing a lot because of this. They just don't want to help. They don't care. Customer care just tell me \ Do what you think
