Cancel lower costing plans because they are not working for the us

Ooh wow I'm under Essential smart dynamic have bern paying for years never used this but only when it was a hospital plan, but since I changed to a medical aid have not used it at all... Few months ago I checked which doctors I can consult in my area Melrose / Bryanston and there were many, even before taking this I checked the hospitals and doctors I can go yo and I was happy then I went on with Essential smart dynamic plan, and now that I need to see a doctor, to my surprise there aren't no more doctors under my plan?? When I called they told me if doctors decide to pull out of a plan they are allowed to do so. My question is why do I have a day to day consultation when I don't have any doctors I can go to??? The only doctor that I seem to now qualify to see or consult is in Benoni, and I'm in Melrose, there's none anymore around my area... Clearly they pulled out of my plan??? Why does discovery keep such medical plans if these plans don't have doctors to consult to??? They can keep the higher costing plans which all doctors go to. This is ridiculous that I must travel all the way to Benoni just because around jhb there's no doctor under my plan.
