Money was not reverse into my account

On the 28 February 2015 I, Yda Klue, bought a ladies watch for R 899 from Extravaganza with my Standard Bank debit card. The following day the watch did not work anymore. I took it back on the 3 March 2015. Extravaganza<br> reverse the payment to an account that does not belong to me.<br> On further investigation I found out that the money was payed into a different account,which has since been closed.<br> Extravaganza admit that they did reverse the money, but into a different account. Extravaganza, owner, Adele was very helpful on the phone, but suggest I must phone Standard Bank myself. She gave me the number of Standard bank Helderberg branch: *** and suggest that I spoke to Shadiya or Marjorie. It is impossible for me to get hold of them. After many phone calls I got nowhere. PLEASE HELP!
