Hello,

This is regarding order # [protected]. It was booked on 05/12 for the occasion of mother's day, to wish my mother on 05/13. While booking, they mentioned it will be delivered between 8am-9pm but they haven't delivered it on-time. There is no way we can reach their helpdesk, it always says busy.
There is no option to cancel your order and if we cancel also, there us no refund will be given as per my discussion with their chat assistant on 05/14. The answered casually that they will deliver on 05/14. Am not getting what is the point of delivering it on some other date if we already missed the occasion.
Am strongly recommending not to use this site in case if you don't want to miss your occasions.
