MIFA PENSION FUND - WHAT IS HAPPENING THERE???

I did not receive my pension for December 2024. When I contact them, on the 23rd of December, they were closed until 6 January 2025. I was there on the 6th (Monday) at 10.45am. I waited quite a long time for the first lady to help me. Then the second lady came. She then told me that my pension was not paid because they had an email out on 20 November 2024 that I had to fill in to say I am still alive. Never received it She then checked and saw my email adress was wrong from September 2023 after my husband passed away. She then asked for my ID which was ALSO wrong!!!! I asked her why I never received payslips or any emails from them....... because my email was wrong!! Their fault as well as my ID!!! She corrected everything and told me that my pension will be paid in by the Friday 10th of January 2025. Nothing!!! The 13rd of January I went back again and then she told me that her manager came back from holiday only that morning and that my pension will be in by Thursday. I received it on Wednesday 15 January 2025. I asked the lady for a payslip and also the December letter that they always send out at the end of the year with the increase. Up till today I did not receive the letter but I did receive last year's December's payslip with the old ID. If you phone, you wait 17 - 20 min ....... if you are lucky. I have the telephone no and email of the lady who helped me......... but I do not think any of those work!!! My pension for this month had a decrease ???? I contacted one of my husband's friends who also get pension from MIFA and he said the "letter of the increase" stated an increase??? What do you do in such a case???? Anybody that can help????
