Refund

My issue with the refund has not been resolved. Because the gentleman was assisting me with the refund says " They won't be able to refund me, There is nothing he can do about my case as he mentioned that I signed for that transaction, Which I'm telling Capitec that I haven't signed to purchase anything for that transaction that's why I was requesting for refund". He says I must go to the branch,at the branch they're not promising anything. They just syas I must come back after 30 days. Meaning this problem of transaction that I don't know will continue happening on my account going forward.
