Dissatisfactory claim process with NMG.

My name is Lesego Modingwane, I have put in claim a since end of January with NMG and was advised that the disinvestment is complete, and an administrator needs to send it SARS, for 2 weeks now, every time I call NMG I get the same story. I was informed that Njabulo Malinga is the administrator who is handling my claim, and I cannot even get hold of him/her on the telephone number that was provided (+***). Can someone kindly assist.
