Netflorist order gone missing.

I received confirmation last night, i.e. 14/02/2019, that a gift I purchased would be delivered. It was apparently delivered after 8:30pm to my recipients place of work however she was not there to receive it. So I have no idea who received the parcel or if it even was delivered. I wrote back within 5 minutes last night enquiring about this but I've received no feedback. Its now well over the lead time of 9 hours. I then tried to call this morning more than once. The number doesn't work. Now I fear that my order worth almost R600 is either ****** or lost. All I need is some help. Need someone to call me back.
