bad service

i joined discovery medial aid in October, then I realized I chose wrong plan. I then call in to change the plan in Novemeber. the consultant I spoke to I assured me that I will be upgraded on the 1st of January 2016. To my surprise this was ever done, I then I called in again to enquire about this. No-one had an answers for me. Subsequently to that I had to pay for my daughter's consultation yet I have medical aid. if no-one is willingto resolve my query then I am left with no choice but to cancel.
