Request for a refund

I placed an order with Herbalife on 12 March 2020, two weeks down the line my order was still not delivered. I then cancelled the order and requested a refund. on 31 March 2020 an employee from Herbalife by the name of Babalwa Alwyn called me and requested that I send her my banking details so the money could be paid into it. I had initially sent my credit card statement as per Herbalife's request that I should send proof of payment before they could pay my refund. To this day I still have not received my money, yet on 3 July I received an e-mail from Herbalife stating that the refund money was paid on 7 April 2020 but I never received it. I request that Herbalife send me POP because I don't know who they paid the money to.
