CELL C CUSTOMER CARE DOES NOT CARE ATT ALL

We are administering an deceased estate and are trying to assist the surviving spouse to take transfer of the deceased contract. When I contact customer service after a long wait I just get cut off. I have not been able to talk to a customer service consultant once. When I send emails to customer service I receive a automated response that that they will be in contact with me with 24-48hours. However no one has ever contacted me. This is unacceptable.
