Where's my refund!?!?!?!?

My game did not come, so I requested a refund, I filled up everything, but they somehow sent me new game instead. I asked for refund very clearly and because of that they told me to return an item to their warehouse. I waited to come, i sent it back and I sent them every possible proof of postage, receipt and all other stuff, and now they don't want to refund me, they dont answer in support centre on website, they don't answer on email, they TURNED OFF support by phone! It worked last week! So im desperate because they need to refund me 78pounds and now I can't reach them.

Please can anyone help me Im desperate!!!!
