Sent humax box back .got refund. But a week later the humax got sent back to me. Saying wrong address. Tried contacting seller couple of times. But No response.
You've let them know, there's nothing else you can do. If they get in touch and want it back they will have to supply another postage label for you to use. If they don't get in touch I'd give it a 2 or 3 weeks and then do what you want with it.
