Refund not forthcoming

After some time of trying to redeem my voucher I finally got an email from the company saying they can't redeem it but will refund me the money. <br> I sent them the necessary info (excluding my bank account details) and now am not getting any response. Just get an automated email reply and there are no contact numbers on their website or emails? HELP!<br> Anyone else with similar problems as see lots of negative posts about them from last year?
