Discovery health stay away

They are *****ing money and very unprofessional how can your keycare plan on a 12000 salary be 5000 per month. Been trying to get a lower plan for 3 months now and they just cant assist. Realy for 2 years ive been overpaying by 2000 a month .can some help me sort these ********* company out thanks in advance. Don't use Discovery rather pay 200 more on a more professional company. Im very disappointed with them and they seem to get away with everything.
