Refuse to pay back my money

Because Nashua Mobile doesn't exists anymore, you will need to take responsibility to get the R 1'209-58 I paid on 13 and 24 Dec 2014 respectively. The payment was accidentally made to Nashua Mobile and not MTN as MTN took over my account from NM since NM closed down. Still, since Dec 2014 and after numerous calls and attempts by both me and MTN, the funds are outstanding to me, so either you get the money paid to me from Nashua Mobile or you will pay this to me. Contact me urgently on ***. Nashua Head Office (which still exists) or NM (if their accounts is still operative) owes me money and I will not stop until I'm getting my money back <div><br></div><div><em>(Supplier name changed from Nashua Communications to Nashua Mobile by Hellopeter.com)</em></div>
