Refused refund and moved booking to next year. Now property has been withdrawn and voucher issued. Now having trouble contacting them (phone line unanswered, and currently no reply to email). A refund should be automatically issued as they cancelled the booking but no, I still have to chase for a refund. Now regret having to involve the bank in recovering my money. Holding onto customers money is not good business sense, especially in the current climate therefore can not recommend the company.
