Extremely disgusted at service delivery

Good Day

I am extremely disappointed in the service that i received from Discovery. I called in on Thurs the 21st Feb and i spoke to a lady who was very unprofessional and refused to hear what i had to say and did not assist with my query. I have been with Discovery for 8 months and on the onset , i was assured that my premiums would be guaranteed for 1 year and now i am told by discovery that my premiums have almost doubled. I am most unhappy and im not receiving whats promised and nor is anyone interested in assisting me . I would like for an investigation to be done and my initial call to be pulled up and for someone to call me back and resolve this issue . I am actually disgusted as to the way discovery treats new clients .
