Three days after Valentine's Day, 1-800-Flowers.com is still apologizing to customers whose flowers and candy never showed up. 1-800-Flowers.com sent nearly 1,000 individual apologies on Twitter, plus more on Facebook, but many customers still weren't satisfied. It wasn't the only flower delivery service with upset customers, though the number of 1-800-Flowers.com complaints appeared to outpace those for FTD Flowers and ProFlowers. Some frustrated customers complained that the phone lines for 1-800-Flowers.com were jammed over the weekend. They also sent emails and filled out online forms, only to receive automated replies.
