con me out of some of my pension

on the 12th Sept at 13 36hrs I was inform that the payment for my pension, would be over R36.000 (recorded) received a letter saying it would be just over R30.000 and paid into my account. My financial adviser, also received information that the payment, would be over R36.000. the correspondence, I left in the hands of my financial adviser. he also sent them a copy of the recording. Momentum as saying that they have no recorded of this conversation. only a conversation in 2017 and not 2018. in 2017, they tried the same thing. so they are trying to con me again! The email from Momentum, were Irene Mncina and Seeshin Nidoo. From my financial adviser Terence Tobin and his PA Salome. Called today and ask someone to call my back. Not a hope in hell!!!!
