Matrix Warehouse - False Advertising!

Matrix Warehouse is currently running a special on a Toshiba 2TB External Hard Drive at R999. I got told they are out of stock, then at the Kolonade Retail Park outlet got offered the same product at R1299. This surely does not comply with the CPA ...? I then get told that the offer was "While stocks last" and this was a different model code / batch. Thing is the ad does not give any reference to the mode code thus this product has to be included in the special as the description is identical according to CPA. I am a regular client of Matrix Warehouse, but if this is the way they run business I would not be supporting them again.
