Canceling my contract.

I've been a member for a year and a few months paying R894pm never ever I had skipped payment. Recently I visited my GP and was diagnosed as stressed. When my GP tried to claim through GettSavvi they were they don't cover stress-related visits. Now bear in mind I was not informed of any of this. Nothing in my mandate/ contract states this and now all of sudden I have to pay for the visit at GP and still pay my premium at the end of the month how is that fair. You guys sell us a whole lot of bull**** when you want us to join and never tell us the fine of whatever plan we joining. I'm canceling my contract with you. This is ****ed up I can't be ill-treated like this.
