Copy of funeral cover contract

I took a funeral cover for my mother and by some reasons i lost the contract, i requested the copy of contract through their call centre (Sanlam Sky) but the lady who was helping me refused to send me a copy and said the policy holder must call her, and the policy holder who is my mother is not in the state that she can make a call. I requested to talk to the supervisor but she refused to transferred me to her supervisor and i felt not being respected and treated well as a customer, and she pronounced me as just a policy payer not a client.
