Discovery Medical Aid - Lack of transparent communication, integrity & poor communication

I had resigned from my full time job and therefore my membership was withdrawn at the end of my last date of service (end of Jan. 2020). I was going to be relocating to Europe at end of February 2020 due to employment and decided I needed a badic hospital plan cover. The agent at Discovery wanted to follow up and conclude on my previous membership had advised and assisted me to transfer to a Delta Core plan knowlingly that I needed just for one month. Today on 19 March 2020 after clarifying with Discovery about this membership (as it should have been terminated end of February 2020 ) that it is still in effect ( even though i am in Europe covered by the social security scheme) and that i need to give in writing notice to Discovery 1 months notice. My concern with Discovery is that it was my own will and decision to request a basic hospitsl plan - i could have opted for another cost effective service provider to cover me in SA whilst i was in between employment and the fact that I clearly stipulated my circumstances when i was discussing it with the Discovery agent. They lacked transparency and failed to notify me at the time of transferring my membership to private and going to the Essential Delta core plan that i needed to inform them in writing because of how this benefit me whilst I am in Europe? I am disppointed in Discovery medical aid because they benefit due to their negligence at my cost!!!
