Bad Customer service

I've registered with Discovery for medical aid and was told that someone else is using my ID number and my account could not be activated, I spoke to Collen Ref number ********** 904 which she was very helpful. I called this morning and was dealing with 2 people who constantly keeps asking me questions even though i gave them a ref number, I need collen to Please call me on the number I gave the consultant. Im having such a bad experience with Discovery and I only joined recently.

I mean for you guys to use my ID on an existing customer for years without even checking if its correct is just unacceptable now I have to suffer to get my account activated.
