Keycare Income verification

For years we have been on a high medical aid. Since I lost my work and started at an new firm with very small income we tried to go on the Keycare Plus aid. We are paying the highest amount for this as Discovery will not verify our income. We have send all the documents needed twice now in 4 months. We can't provide them with anything more to confirm our income. We send payslips, bank statements, joint account info and my husbands annual income statements. Discovery health are looking for reasons not to lower our premium. We will try other medical aids now. Very disappointed.
