Huge fail!

I booked tickets when it first became available. Then they had to change the dates due to the fact that they weren't prepared. I requested a voucher so I can book new dates. They sent me voucher codes but it didn't work and after numerous emails and requests for assistance, I asked them to refund the money and I was getting no joy from them. They requested my bank info and said that the refund can take up do 30 days. It has now been 2 months and no refund has been done and no feedback from them. I am so disappointed with the lack of customer service and I feel sad that a company like that can keep on doing this to people as I know I am not the only one struggling with this issue.
