no help what so ever

On the 2nd of march i sent an email to cell c to inform them about the passing of my mother who had a contract with cell c, the contract was in her name but the number was used by me has she took the phone for me while i was still at school, i have asked cell c to move the number to prepaid so i can still keep the number, i have been calling and it seems NO ONE in that department has any idea on what to do next, i was told to get a new sim card and rica it, they told me to give in the new SERIAL number and the line would be open.

i did that but they keep telling me to resend the documents and wait for them to give me a call.

i have a huge problem becasue now i am unable to make any calls or anything
