Received an email claiming delivery failed even though recipient was at home. No phone number exists for Serenata or for the courrier they use - spoke to Serenata by email and was simply told they'd "keep the flowers in the van and try again tomorrow". Completely unacceptable service - they refused a refund, refused to reattempt delivery that day and refused to exchange for a fresh bouquet the next day. Will never use this service again and do not recommend to anyone.
