Liberty stalling payment of my money!

I left my job on the 28th September 2018 and submitted the required forms to my HR. They went on to submit the forms to Liberty and I have yet to receive my Provident fund payment. I have sent countless emails and received conflicting information to the point that I became frustrated with my HR team and investigated whether they sent the forms or not. I received evidence from the HR team in the form of a forwarded email containing all the required documents sent to Liberty. I then mailed Liberty and attached the email from HR to prove that they had the documents required to process my claim. I received a response on the 14th January stating my payment would be processed by the 23rd January. It is the 25th and after sending yet another chasing email, I do not have my money or a response to my email. This is incredibly frustrating that I must be given such grief to get my money!

Can someone just please get this matter sorted?
