Terrible online shopping experience

If i could give them negative stars I would. I ordered something small for my wife to be delivered on Valentines day, paid and received confirmation that delivery would take place between 9am and 5pm on the 14th. On the morning of the 14th I received an email from Lee Robertson saying that the item could not be ordered individually, that is an add on to a flower order, and I should send my bank details for a refund. I responded saying that it does not indicate anything like this in the item description. I then received another email from Josie, same email address, thanking me for my order and how grateful they are for my business. I subsequently sent another 2 emails asking what was going on and have not received any response. I am appalled by this service. Firstly, it is not the customers responsibility to make sure that their website enforces their business policies. Secondly, an online shop that doesn't respond to emails should not be in business.
