Digital door

I went to Builders warehouse in alberton. I spent over R15k on their merchandise. I wanted a digital security door. The lady said they do not have stock but will do a transfer for me from Edenvale. Now upon my arrival i find out that the edenvale branch refused with the digital security door lock because they only have 2 left. Are they keepinghe stock or selling the stock. I need this digital door. <br> <br> Somebody help<br>
