Look towards other flower delivery sites, there are plenty out there with punctual delivery.
07 MAY 2020 - SINGAPORE TL;DR will never be patronising their services further. I made the purchase on their website on 4th May for a delivery on 7th May(9am to 1pm) as I working during the Mother's Day weekend and wanted to surprise my Mom before then. Come 7th May (Vesak Day) not only did the Mother's Day flowers not arrive during the window, time check now is 5.36pm and the driver who has still not dropped off the flowers had the audacity to inform his company that the order HAS BEEN DELIVERED; delivered to whom I am still wondering when I have been home waiting all day... The customer service line with a terrible headset receiver(filled with distortions and echos) and agent whom I spoke (Natasha I believed) and later texted me to say the delivery team made a mistake in their delivery timing as they thought that it was for an afternoon time slot and that they would be arriving soon; I spoke to them at 1.12pm, 1.55pm, 3.31pm and convened with them on Whatsapp thereafter. Natasha was pleasant but I'm sorry, no amount of apologies or compensation would be able to lift the frustration and my time wasted waiting. I had to order food delivery incurring delivery charges when I could have stepped out for a quick grocery run or take-away during this Circuit Breaker(lockdown) period. Update: 5.50pm the flowers have just arrived with warm water and condensation inside the vase, when i queried the delivery personnel he mentioned that he had only been given the flower about an hour ago, which completely contradicts everything the customer service had said thus far. Those flowers must have been sitting either in the warehouse or van long enough for warmth to be build up inside the vase; finger pointing between delivery personnel and the office. The flowers also arrived in a different vase design from what was advertised on their site and it just adds to the list of my disappointment with them. For the money that you would be spending, I would suggest you consider some place else.
