ZERO COMMUNICATION - MEDICAL SUSPENSION!

Discovery has failed to update my telephone number for yrs. The last time we had this issue was last year when my prem increased and they blamed me for not knowing this because my number was not updated. I had many times updated my number, like I did last year and again today I realized talking to discovery that my number was STILL not updated.I went onto Discovery today to see if I could add vitality, only to see my boyfriend on as a dependent. I did an online appl last year, to find out what it would cost for him to be on it, little did I know that the application was in fact activated. Due to zero correspondence from Discovery, my account is now suspended because I had not idea my premium had increased for an extra dependent. I hear from a consultant today it is because I clicked SUBMIT it automatically adds him. Surely someone should contact me to advise the changes that have taken place and the increased premium. Surely someone should contact me if my medical has been religiously paid for more than 15 years. I have an 8 year old. Besides that I've been having blood tests and xrays which will now not be covered - Zero communication from Discovery, not by phone, email nor post.
