False advertising on promotion laptop

I wanted to purchase a Asus pentium processer laptop as advertised till 29 Feb 2016 for R3999. When I started to ask about the features the laptop they were advertising it was not a Pentium processor but a Celeron. It was a complete different product. When I pealed off the label is showed Celeron. By putting an other product's label on it does not change the actual product. I asked them why they false advertise and the manager could not answer me. I requested that they order a asus pentium processor laptop from head office but they refused. The product was also a 2nd generation processor and not a 3rd generation as advertised.
