Where is my refund?

Review is meant to be a one but that is too high. I have battled since 15 Nov to get a refund as I immediately cancelled my order in store after placing the order. Was told I could pay half the amount as a deposit and the full amount was deducted. I cancelled at once and am still waiting for a refund after numerous promises and excuses from Des a senior in ghe business. She has promised the payment is being processed and she will send the proof of payment. Still nothing and no response to any questions I ask eg when can I expect the refund. She also told me some finance dept had to assist, they certainly don't need to wait for any finance dept to get my payment or money or any customer's for that matter. I was also not told delivery would only be early Dec. Only after I had paid. I would like a full refund as promised and I have requested and donnot understand the delay and get no answers about the delay. I in fact should get some interest by now.
