Sound bar missing the Bluetooth remote.....query

I bought a telefunken sound bar from them,on receival of it I noticed that the remote was missing,emailed them numerous times & all they keep telling me is that they are trying to reach the supplier / that they've reached him & the remote will be delivered. Nothing they've said has happened & it's now over a month,I am unhappy about their service even asked for my money back but they keep responding about the supplier this & that. I mean they are at fault for not checking the goods that they sell to us before shipping/delivering it.
