Bonitas Medical aid failing to provide bare minimum service

My refund was due in May as per your previous communication, after re sending the same documents they seem to repeatedly require.

They kept quiet until I made an inquiry on the 9th of this month. On the 16 June they then demanded a colored copy of an ID which i provided though I fail to understand how it differs from a Black and white one as long as it is clear and certified.

I have send it, On the 22nd they are coming with another demand for a latest statement, because the one they have is over 3months, who's fault is it that it has surpassed 3 months? I gave it to them on time, The incompetency on their side is affecting me since they demand a bank stamped statement as the verified computer generated is not good enough for them now i must leave work and go to the bank.
