Momentum Head Tracey Basson :cant release the living income from 1937 to 5000 as requested

retirement income option . i am doing this on behalf of my father who investment is at Momentum . they give him 1937 monthly . and in november they write a letter that the living income should be increased to 5000 each month. Now they said they never received the documents and they decreased the money to 1768 . My father is unhappy as he is done this and sending all the documentation so the 5000 should kick in in January . Now they sent a letter stating that they decreased the monthly funds to 1768. as they never get any correspondence from my father . I would like to report to you and assist us as my father is suffering because everything needs to be paid in that 1937 .. there food ; water; electricirty and medical expenses the 1937 was not enough hence he needed the 5000 . so now they keep on sending him from pillar to post . everytime he visits Pe Branches stating that money will be deposited in 3 days but nothing .
