IT IS DUE TO ME - GIVE IT BACK

I requested termination of my services in Jan 2018 for end of Feb as I was told that I needed to give a 1 month's notice. Paid my subscription on the 02/03/2018 which was [according to my knowledge] for Feb month, only now I just realized that my services were terminated as of 31/12/2017. I inquired [on a live chat] on my refund and was told that I needed to send through some docs [bank details confirmation and ID copy] - which I did on the 18/05/2018. Received a response that I needed to send through an affidavit if I'm currently not on any medical aid - I did that this morning and received a response that I need to send through my current medical aid membership certificate. WHERE DO I GET A MEDICAL CERTIFICATE WHEN I AM NOT SUBSCRIBED TO ANY MEDICAL AID? THE RIGHT HAND DOES NOT KNOW WHAT THE LEFT IS DOING AND EVERYONE DOES AS THEY PLEASE, WITHOUT CHECKING THE ACCOUNT HISTORY . - WHY WAS I TOLD ABOUT A MONTHS NOTICE AND YET YOU IMMEDIATELY TERMINATED MY SERVICES? - WHY NO ONE REALIZED THERE's A POSITIVE BALANCE IN MY ACCOUNT - WHY WAS I NOT TOLD ABOUT ALL THE REQUIRED DOC'S FIRSTHAND? STOP SENDING ME FROM PILLAR TO POST AND PROCESS MY REFUND.
