Discovery Health 70% increase for dependant

I communicated with Discovery two months ago and have still not received an answer. I was under the impression that my daughter (a student) who turned 21 would still be a dependant, but her membership has gone up by 70%. The result was that the stop order could not go through.

I cannot afford (as a widow and a pensioner) to pay in excess of R10 000 pm for a medical aid. The customer care line could not assist me and gave me the wrong number to call.
