3 weeks later. No refund to my bank account

Order number ********** 3

I placed my order in mid-December for a light and tv mount. After paying then i received the delivery dates. The delivery date was too far for me to wait for the TV mount so i cancelled the order. I requested a refund (12 December) to my bank account. Upto now 7 Jan I have not received the refund.

Then the light. I received the light but it was not the one that i saw online. I logged a return for the light. It was collected and my account was credited. I then requested a refund (28 December) to my bank account because i have already bought another light somewhere else. Upto now 7 Jan I have not received a refund.

I have spent about +/-30 minutes on the phone with your consultants over these weeks. I asked for a proof of refund showing my bank details but nobody has sent it to me.

How much longer do i need to wait for the money to be transferred to my bank account?
