Frustrated client

I have been trying to receive a portion of payment from pension, since October 2021, when I resigned. Whenever I make a follow-up, the call center agents keep shifting the dates. On the 27/02/2022 I was told the payment will be made on the 3rd, I called on the 3rd I was told it will be made on 7th and the 7th I was told the payment will be made at the end of business. On the six I was told I need to submit the Nedbank statement to prove that the account is and I don't know what did they do with my FNB statements I submitted withe claim. I submit the statement and checked on the 9th to assess whether did they receive my statement and the confirmed and it will be processed with 5 to 7 days. I made a follow up today and the agent start the process again telling me it wasn't done on the 9th. Frustrated client
