SALA PENSION FUND DREAD DISEASE NOT PAID

I have been with SALA PENSION FUND for 15years as an employee of Mangaung Metro Municipality. Upon my joining to the Fund, I was promised to be paid in case I was to be diagnosed with a Dread Disease. In 2015 I was Diagnosed with Stroke and after 8 weeks of Rehabilitation and treatment I gracefully recovered, to my disappointment the Fund rejected my claim on the base that I have recovered, according to them my claim could only be valid if I was permanently disabled. These is not the obligation agreed upon and I feel it is unjust to me as a Member, worse I cannot get assistance I am **** ti feel like unreasonable or mentally unstable. Please help.
