Exchanged some Tesco clubcard vouchers for Chessington World of Adventures, the valid until dates on the CWOA vouchers is 31/12/2010, this leaves me with just a couple of weeks to use them, BUT, Chessington World of Adventures is closed so this leaves my vouchers useless, why do they put a date that is not actually valid on the vouchers? How stupid, who should I complain to, tesco or Chessington W of A?
