Saving refund - no communication after 6 months

I have been following up, and requesting for my savings refund payment since April, it is now June. No communication no nothing from Bonitas. I so f** hate this medical scheme, thi organization is so frustrating. I regret the day I opted for this med aid or organization as a whole. How long should 1 wait for a feedback, I want my refund. This is the last I will be writing on hellopeter coz it seems like no one gives a damn about reviews. 1 must take further steps up.
