Unpaid refund

2 months ago, I requested a refund from my Mr Delivery wallet. The company processed the refund into an account that does not belong to me & now they do not want to take the accountability for it. Instead, they are busy with "investigations" yet my refund has not reflected into my account. I have sent my bank statement a number of times but still they choose to not refund my money. I am at the point of having little to no patience with them.
