Extra Billing

I has emerged recently after I resigned from my employer that Discovery has been billing me extra ordinary.I met Discovery Representative in Pretoria,I told him that I need a better health cover for me & my daughter as the current is to difficult to maintain.He recommended me classic saver based on my income.I was actually dissappointed to discover that my daughter(3 years) was billed as adult for the past 3 years.He recommended me same cover,hence I need my money back for all those years in order for me to continue with Discovery
