I had a coupon for Lunch buffet for a couple which was expiring on 30 Jun (Sun).. My parents who are senior citizens visited Radisson Sec55 Noida with great enthusiasm to have the buffet. However when that presented the coupon they were told that they have a special lunch that day and hence the lunch buffet cannot be availed. My parents requested several of their staff members on duty including their manager but no one was ready to help.. Finally that had to return home without having food.. such a heart break and humiliating experience mented to an old couple.. that too after being a member of Radisson Sec 55 hotel after having paid Rs 8000 as membership.. Extreme insesistiveness. Not acceptable.. Meanwhile my voucher also expired.. will not recommend this hotel to anyone...
