You keep putting me in the wrong income bracket

I have been trying since OCTOBER 2014 to correct my income details with you, numerous emails was sent between us, and this problem is still not resolved. I have been trying to contact your offices telephonically but without success. I either have to wait a at least 20 minutes to get through and when I do I keep getting transferred. <br> <br> THREE PAYMENTS FOR R1632.00 has been deducted already !!!, After I received my new contribution payment I informed your offices that I cannot afford this premium and if this is the payment confirmed by you. I don't understand why it's so hard to understand as I have forwarded all the requested details that explains in detail how I don't fall into that income bracket.<br> <br> Must it really be this hard to get someone competent to speak to me?
