Builders Warehouse using online platform to **** customers.

I ordered online 3 Cubic River sand on 26 April and paid including delivery fee order number ***. They indicated that they will deliver on 15 May. I waited patiently until the 15th and there was no delivery and no communication. I waited a day hoping maybe it was a slight delay and still nothing came. today the 17th, I enquired through their online form an also sent an email early morning and there was no response. I then called the call center to check and the consultant promised to follow up and call me back within an hour. Within an hour, another consultant called me, not the one I had spoken to earlier, only to be told that the river sand is out of stock so I have two options, either to cancel or wait and they are not sure when they will have stock, I just have to wait, no indication of potential delivery what so ever, meaning after having my money (ofcourse together with other similar customers money) for more than 3 weeks, having invested it and earn interest, they just want to pay back and if I cancel they are not even sure when the money will be back in my account. Truly Builders warehouse that we used to rely on has joined a group of ****mers who do exactly the same and make millions over night by investing people's monies. Now I am stuck and things are not stopping to go up, meaning even if I get the money now, it's not going to be enough to buy the sand. Can you believe that Builders warehouse, as big as they are with so many branches does not have river sand? Not even an attempt to get stock from another branch if the one closer to me is sure that they do not have. I then checked for the same from the next Montana branch and the same sand is now costing twice the price and that's why they are frustrating me so that I cancel. It's so painful to be ****med by such a big brand. I wouldn't mind if it was these small shops, not Builders Warehouse newly renovated Gezina branch. Really disappointed. I still don't believe that a big brand like Builders Warehouse may run out of stock from all their branches but want to charge new prices for old orders which is a ****, that's why they are so quick to say you can cancel.
