Consultant did not delivery on her Promise

I have been calling and holding on for 30 minutes before I get a consultant, Megan answered the call and said she will assist me with the requested proof of payment and I held on for minutes before I decided that I cannot hold on anymore, I have sent Hayley Viljoen so many emails I have lost count and she initially made a promise to me that she would follow up and provide e with the required proof of payment and she never came back to me. I am beyond upset with the customer service I have receive from all consultants I speak to, Twice I called in holding on for extremely long and and was promised that I should give the proof of payment 30 minutes and its on it way, Kindly send me a proof of payment for MFC, Is this so much to ask.
