Missing Funds

On 01 March 2016, my sister based in the United Kingdom sent me R 30 300 (almost GBP 1 500) via bank transfer. This money was meant to clear within 2/3 working days. After 7 days, I went to the Standard Bank Musgrave Center to inquire if they knew the status of my incoming transfer. I was told to get in touch with the International Banking Center, Johannesburg. On calling them, I was informed that they had indeed received my money. I then asked why they had not gotten in touch with me, which is what they are supposed to do once they receive cash on your behalf internationally. The consultant I was speaking to could not give a reason, just that they were going to do. This excuse despite the fact that this was 7 days later. They then informed me my account had been closed so I requested a reversal of funds. This was on 08 March 2016. Today is 28 March 2016 and the money has been missing for 3 weeks. No one can tell me exactly what happened during the reversal and I am now facing eviction due to non-payment of rent.
