Unacceptable service

I am extremely disappointed in the service I received from NetFlorist. I ordered an item last week Wednesday. I put in the area where I want the item delivered, chose the item and then they let me know it can not be delivered to my desired location, which is fine. They said I could choose another item and gave me list, which I did. Again, this item could not be delivered to the location. Fine. They suggested an item, which I then accepted. They apologised and gave me a R100 voucher for my next purchase and promised this item would be delivered on Monday.

It is now Tuesday and this item is still not delivered. I emailed them at 9am this morning, with no response. This is really unacceptable and I insist on a refund as I will not be using this service ever again.
