OMW.....WHAT POOR SERVICE

My wife left the service of Lewis stores on 12/3/2015. She completed her withdrawal form on 27/3/2015. NMG indicated it will take 6 - 8 weeks for payout. On 11 May 2015 my wife called and was promised that payment will be in 8 -10 working days as they are waiting on SARS for the directive. On 25/5/2015 we called again and was promised AGAIN that directive will be sorted the next day and payment will occur. On 28/5/2015 no payment was recieved and we called again, we were told that the directive will be sorted out the friday and payment will occur. We then went to SARS and they indicated that no directive was requested by NMG.We then called Natasha gain and ask why she **** to us on which she dropped the phone in our ear. After that she did not pick up her phone or dropped it as soon as she hear its us.On Monday we contacted SARS again and they indicated that a directive was requested on 28/5/2015 and finalised on 29/5/2015. From the 28/5/2015 we just could not get hold of Natash anymore. I even send an e-mail on the 28/5/2015. NMG accepted the e-mail, but no response as yet. WE really dont know what to do anymore..PLEASE HELP!!!!
