No delivery on Valentines day as Promised

I am absolutely appalled at the service I have 'received' from Netflorist. You can not even call it a service. I placed an order for Valentines day, selecting 14.02.2018 as my delivery date. After my payment had gone through the date was changed to the 19.02.2017. I immediately called the call center. The lady I spoke to promised me that my parcel will be delivered on 14.02.2018, I have a recording of this. I called numerous times on 14.02.2018, wasted over R200.00 airtime and still no delivery. I have even emailed. They respond stating they will respond in 9 business hours. Surprise, 2 days later still no response. They messed up our valentines day. I am livered!!!! I have the recording if required.
