Bad service

Good morning. Can you please help me with my refund from YDE, I've been in contact with them since April but with no help. I ordered online and paid with an EFT but was later advised that the account provided on their site is of Truworths. Then I was advised to send bank statement for a refund of which I did. Since I provided them with that they cant seem to refund my money, I'm sent from pillar to post without any help. My order number is: 803002E340. Please assist.
