Clicks online order

I placed an order online for collection at the Randfontein Click branch, when colleting they noticed the wrong item was sent to them. According to the branch they advised the wrong item was sent and I was to advised to send an email regarding this, which I did and to date I am only getting my mail has been forwarded and I have been getting nothing I requested a refund and only get the same response. I have been sending email since the 6th Dec, and still nothing, I did not get a refund nor the item I ordered.#I will never buy anything online from CLICKS again.
