Provident Fund not paid out

I resigned from my company and requested that my provident fund is withdrawn. I send all the documentation through. I received an sms on 09 April to say that my payment has been rejected due to an automated bank validation process and I must contact AF. I did so and Fazel informed me to send through a bank stamped statement and a certified copy of the ID which I did although the error was on AF's side. I phoned an unfortunately did not get the consultant's name who confirmed that my documentation has been validated and the payment will be actioned. I did not get the funds and phoned again this morning. I spoke to Nollie who informed the consultant I spoke to on Friday did not send the documentation through to the correct department and she will do so this morning. It will take another 3 days to get the payment actioned. It is a large amount of money and AF is getting the interest on the funds. This was the worse experience ever and if I can help it I will not invest any money in AF. Their call centre on average takes 15 minutes before they answer.
