Tried to send flowers to my daughter as an unexpected surprise to congratulate her on her exam success as her husband is away. Sadly M&S flowers use Yodel for delivery who made little attempt to deliver them despite her being at home - one of the advantages of tracking. M&S were unable to help as Yodel customer service close at 1pm on a Saturday. They may try to deliver again on Monday, it isn't clear, but she is a junior doctor working 9am-10pm so she definitely won't be in then. I would have expected M&S to use a more reliable delivery service given the prices they charge.
