AWFUL SERVICE!!!

Two incidents - Incident 1 - I called to move my reservation within the 24 hours listed to the next day. When we came the next day after we were seated they told us they used our voucher the previous day despite admitting they got the canallation. <br> Second incident - the restaurant wouldn't let us book as they were full. Asked for a refund before the voucher expired. Groupon delayed in replying by 5 days now won't refund because the voucher is expired as a result of their delay.<br> They completely breach consumer rights!!!!
