GEPF Incompetency

GEPF:I asked them if I can submit beneficiary nomination forms per email and they agreed but when I submitted per email I was told it's not acceptable. They then gave me postal address to use, which I comp**** to. Submitted per post as their instruction, beneficiary nomination forms in June 2020 up until(07/09/2020) now has not been processed. Everytime I enquire I'm subjected to so much rudeness from the customerservice staff and there is nobody to escalate the matter to. The call center agents are so rude because they know that there are no contact details for escalating the matter.
