NMG Benefits are ******.

These people ****** me off my provident fund payout. I needed a payout of R25 000 and had requested them to send me an IRP5 certificate from sars so that i could see how much i would be taxed. I was taxed around R4000 and then i expected my balance that would be paid out to be around R21 000. I instead received R12 000 from these people. What happened to the other 50% of my money?? This company is the worst and i am looking for legal assistance with this ********** action.
