Refusal to pay my Pension

I have been awaiting my pension for over 2 months and when I communicate with the call centre or try send emails they take forever to respond. The call centre said it takes 4 to 6 weeks for the payout. Sanlam keeps stating my previous employer didn’t send documents and my previous employer says they did. I personally sent them all the relevant paperwork, but it’s seems that they are not interested. Sanlam refuse to send me proof of the above when Rael from the call centre stated that he would send me the email correspondence. I keep being pushed from pillar to post, this is unacceptable and want my monies. The call centre is beyond pathetic as they take over an hour to answer theirs phones and don’t know what is going on.
