Disappointed by Sizwe's non-payment of claims

I am beyond disappointed by the treatment I received from Sizwe. I have a claim which they have not settled since last year September. It's almost a year to the date the claim was made however, no payment has been made. My 2 dependents received treatment on the same day and only one bill for 1 dependent was paid even though the statement had 1 total amount showing as the balance. the payment was split, and no one can give a valid reason as to why only 1 dependent's bill was paid and the other still outstanding. I have called and I cannot get a proper response and no response is ever received from emails. Truly pathetic customer service!
