WesBank, kindly pay my refund

Renault Northcliff and Liquid Capital sold me a flawed service plan in September 2020. Phumla from Renault Northcliff tried to assist but neither Renault nor Liquid Capital wanted to take responsibility. Consequently, I requested Liquid Capital to cancel the plan. They did and subsequently paid the refund to WesBank. However, my refund is mothballing at WesBank. After I approached them about it, they requested that I provide them with proof of payment from Liquid Capital in order for them to pay it into my account. WesBank acknowledged receipt of the funds but insist on that proof. With regards to that proof, nothing is forthcoming from Liquid Capital, communication with Andre Pillay has yielded nothing but a waste of time and mental anguish. WesBank, please my refund, I need to service my vehicle asap.
