False advertising

I went to the Cresta store yesterday with all the documents needed to open up a new contract. I was interested in the current promotion (5GB Telkom data &MiFI LTE router for R99pm for 24 months). I was told by one of the consultants that this special is for the first 1000 customers and it is now over, his manager will decide by Friday if they can still continue with the special and we must come back and check. I unfortunately did not get the gentlemans name as he was not even using a name tag. My issue is that there is no indication of this condition on website or any advertising. It is being put forward in all forms of advertising as a March special. You need to get this store sorted on the advertising, this is unprofessional and gives potential clients the wrong impression. You also need to confirm for me if I can still get this special
