Refund (reference Order EV4181)

I purchased a camera from Evertrend and it was delivered on the 10th January 2025. I am not at all happy with this product and want to return for a refund. As stated on their T & C it must be returned within 7 days for a refund. I emailed term on the 14th January to find out the procedure for collection, to date nobody has responded and tomorrow the 17th January is the 7th day
