Poor service

So I closed my Nedbank account a few months ago because of how unsatisfactory it was for me to bank with them. In April when I was still banking with Nedbank I made a purchase with Shein and now they have to refund me some of the customs as I was overcharged. They can only refund into an account that was used when payment was made to them. I contacted the Menlyn branch to ask if it's possible to retrieve money from the closed account and the lady I spoke to said yes as it goes into what you call a suspended account. So today Shein sent a notification that the refund will be made after 2 business days therefore I decided to send a dm via twitter to nedbank to ask how I will be notified when the money comes through? The Twitter account handler was like no it is impossible to receive money into a closed account therefore it will be reversed. I'm upset at this contradictory statements between the lady I spoke with over the phone when I dialled the menlyn branch number and the twitter account handler. Can someone from Nedbank contact me and give me a clear answer and way forward. Account number was ***
