No delivery on specified date

Good day Builders

On the 29th of December we purchased 2x water tanks from the Paarl Builders depot branch. While selecting the items, the delivery date was displayed as the 30th of December 2017. Upon the checkout the Payment confirmation stated that the water tanks will be delivered on the 2nd of January 2018 (Today). On Saturday the 30th of December 2017, we did not receive any feedback/update on the delivery. I contacted the store, with no answer. I then contacted the call center, at 10:55am the lady that answered said the store is experiencing an technical error and that she is also unable to get hold of them. She assured me the tanks will be delivered on the 2nd of January 2018 as the deliveries are dispatched a day in advance.

Today we had to put in unpaid leave to be present for the delivery. When I contacted the store, there was no answer. I contacted the call center and Nandy/Mandy stated that the store is closed until the 8th of January 2018, a fact that was not stated on Saturday. She then proceeded to state there is no stock available and there is a backlog. I asked to speak to her manager and she transferred me to Mymoenie.

Mymoenie stated that there is a fault on the website and that she is in contact with the head office to rectify the problems.

I would like to understand when my tanks will be delivered, as the money was paid and is accumulating interest in your bank account. I would also like to be compensated for the unpaid leave we had to apply for, as its a day wasted due to your error. Please refer to the delivery date on the attached picture.
