Cover dependants without my consent

I asked for quite for my parents the added them without my consent now my medical aid is suspended as we speak , I have send forms to terminate, now no one answers my emails only the machine with ref numbers . It's been 2 weeks now that I'm going back and forth I even asked people that I dealt with on emails to ask their team leades to call me or assist with no luck . Yesterday I received a reminder that I owe the R17644 and my premium is normally R5250 which was debited last month. But I'm not covered as we speak. I am very disappointed paying but I'm not covered only because I requested a quote and someone decided to add dependants.Now I must suffer because of their nit caring.
