Poor performance

I first phone on the 9th of April to ask about the funds that is uncleared, and I want to dispute it. they took my email adres and forward me the dispute form. I have sent it the same day back. Than i do a follow up on the 14th of April, shock to hear that they haven't receive my dispute form, so I resend it again. I talk to Gloria maswabi and i even send it again to her email adress, than she said she will make sure the dispute department gets my form. I phoned 28 April and ask how far is my dispute, the guy Mpho let me hold for about 5 min just hear that he will get back to me before end of business because he needs to discuss the matter with his team leader. No response.
