Sanlam Employee Benefits Claim service support non-existent

I would like to lodge a complaint over delays by Sanlam to pay out my Pension fund claim. I changed jobs in January and opted to withdraw funds. I have since been waiting and receive 0 comms/ feedback. I have tried contacting Sanlam via their e-mail but to no success. This morning I tried their WhatsApp, and someone answers almost immediately. However, the moment you start to query the claim, they send you automated responses in a split second then they hang up on you before even attending to your query. This is one waste of a service and I have had pathetic service from 2 consultants - one Kyle(twice this morning - who immediately hangs up), and one Mbali who only greeted then went silent for almost an hour. The last I got a response was end of Feb when they said I needed to update my SARS details. I updated SARS the very next morning - and I sent Sanlam the confirmation letter the very same day (3 March 2021). However, one response from Kyle was that I need to send the confirmation, but before I could explain he just went off the chat (have copies of the WhatsApp chats - together with the times that they responsed and exited the chats)

I expected at least some form of customer service, but this has turned into a snowball of no comms and no delivery on Sanlam's part
