Incorrect billing and put underpressure to accept their mistake.

I have spoken to 3 different people on the same matter since Thursday last week. I am still not getting any joy. Andiswa, Palesa and today Monique. it turns out Discovery wants me to pay for cover/benefit I did not enjoy. I added a spouse to my cover on 1/10/2018. he was a discovery member too but we were on different benefits for our vitality. they gone on without informing me or seek my permission and integrated our vitality cover. only they are different. so they decided on their own to debit my account to cover a period that has passed, that i never used. apparently this is how it is my Monique. I either choose to loose the benefit or pay for one i did not achieve. not my circus, I was not informed therefor not willing to pay for their mistake. You've been warned.
