Unfair dismissal and treatment

Sanlam Sky solutions, based in Houghton, unfairly dismissed me for underperformance, prior to correct processes being undergone prior to such a dismissal being taken place, I and many of the employees currently employed in the contact centre are treated unfairly/micro managed without clear reasons for such treatment being conveyed, I believe the superiors worked collectively with HR to cook as much information to not retain me as an employee who once a top performer, promoted to a better position and excelled there too, but later lacked in performance, but instead get me dismissed but all means necessary, I'm disappointed as ex-employee and holder of a sanlam policy, truth be told I will terminate my policies and I would never recommend such services to anyone. I've lodged a case with the CCMA coz I feel a huge Comapany as Sanlam Sky Solutions should not get away with such unfair treatment.
