Ordered £50-worth of Mother's Day flowers 2 weeks in advance. Got a "Dispatched" email at 9am on Mother's Day saying they'd arrive between 11:23am and 12:23am. That was the end of correspondence, the flowers never arrived. Serenata have no phone number, just an email address which will give you a response in 48 hours. I Tweeted, I Facebooked, I emailed, to no avail. The next day I got a very unhelpful reply on Facebook, saying the delivery was attempted at 11:45am, but they couldn't find the house. I was not notified that a delivery was attempted and failed. Serenata had my mobile number, home number, and email address. If they'd told me at 11:45 that no flowers would ever arrive on Mother's Day, I could have bought some new ones in time. I've been trying to dispute this for 2 days now, attempting to get my money back. Serenata tell me that it's my fault, telling me I gave them an incorrect address. I gave them the full, correct address used successfully by Royal Mail, Amazon, DPD, Hermes, and the bloody UK government. No flowers delivered on a day chosen 2 weeks in advance, and no refund. No customer service number, no response via email. Facebook Messenger crew useless and indignant to their own failures. At 10pm on Mother's Day I ordered a much bigger and grander (and cheaper) bouquet from a local, independent florist. I gave them the same address I'd given Serenata. At 9:30am the NEXT MORNING, the flowers had arrived. Never rely on Serenata, they do not care, and they won't refund you if your flowers don't arrive. £50 down the corporate drain.
