Struggle to get money repaid into my account

I paid in money into my closed Woolworths store account. I paid the money accidentally into the Woolworths account that was closed in February which means the account is not supposed to exist any more. Woolworths credited my account. All this happens on 5 December 2019. I contacted the missing payments department on 6 December. They promised to respond to my email which never happen. After this I contacted recoveries at Woolworths financial services. They also promised to respond in 48 hours. They also promised to respond. I received no reply as well. After this I I contacted complains department today and they referred my email to recoveries. I also called recoveries personally and they promised to respond in 7days. Since 5 August I drove to many stores in order to get my money paid back to me. I am a single mom and will not be able to buy presents for my daughter. It does not look like Woolworths care about resolving the situation. Can someone please help!
