Query: Frustrated with delivery time

I should have heeded the warnings of the previous reviewers.Ordering in plenty of time for the shipment to arrive, I was informed upon payment that the plant would be delivered by Mother's Day, but after placing the order, I see that it will take at least 3 weeks (2 weeks *after* Mother's Day!) AND there is NO OPTION TO CANCEL MY ORDER.Trying to reach Amazon is next to impossible.I could not be more dissatisfied.
