Delivery rescheduled on multiple occasions

I am extremley disappointed with the delivery aspect of Superbalist.com . I am no stranger to online shopping and have never had an issue with delivery , when ordering from Zando, Spree and Takealot.This is the first time that I have ordered from superbalist and I am shocked at the 'relaxed' approach taken to delivery dates.

On the 30th of November 2017 , I recieved a text message stating that my order will be delivered on friday the 1st of December 2017. I waited patiently for my order on friday , only to recieve a text message at 17:17, saying my order has been delayed and will now be delivered on Monday the 4th of December.

On Monday the 4th of December I recieved a text at 10:42, saying that my order will now be delivered on Tuesday the 5th. I contacted the concierge at Superbalist and had been told that my order will be delivered on the 4th before 5pm. After speaking to the concierge, I recieved another text saying that I will be recieving my delivery today before 5pm (4th Dec 2017). I waited for my package to be delivered today , only to recieve another text stating that my order will now be delivered on the 5th of December ( I recieved this text at 16:16).

I dont know if this is common practice but I assumed that delivery dates should be honoured as time is valuable and not all of us are able to stay at home on multiple days , due to a change in delivery. I have spent another day waiting for a package that has not arrived, I will now have to wait again tomorrow for a package that might not even turn up.

Superbalist seems to offer a wide variety of products, it is a shame that the courier company they use is incapable of following through.

I am unsure as to what I should do at this point as I have already wasted two days of my time.
