Rude Customer service agent puts phone down in my ear.

Called to get a full comprehensive list of Doctor's for my Mother in law in the Garden Route. Customer service representative could not telephonically give me the list of Doctors over the phone. She wanted to request an email be sent to me with the list. I told her they have previously sent a list but it was not complete list as there was only a few names on the list. And non of the Doctor's where suitable. I signed up my Parents so that we had peace of mind when they got ill. This has been a nightmare, from incorrect cards being sent out with incorrect names and incorrect date of births, there just seems to be no responsibility or accountability with this company. Horrified. The sales Representative "customer care" tells me to calm down she wants to help me. Lady putting a phone down in a client's ear and when she phones back putting it down a second time will get this contract Canceled. Not on
