Cell C False advertising

Since beginning of December, right through January and on their newest deals booklet which is valid until 13 March 2019, Cell C is advertising Iphone 7 32Gig and 7 Plus 32Gig deals, but according to their call centre they do not supply these phones anymore, only Iphone X. To me this is FALSE ADVERTISING. You cannot advertise a product on a special price if you do not stock it, and don't try to tell me it is sold out as we've been trying since beginning December, and in your newest booklet it is still advertised - even though you did not have stock for the past 60 days... All the branches sits with 64Gig and 132Gig, but you cannot get them on the same contract than the 32 gig - according to the CELL C shop assitants they are more expensive than the Iphone X contracts... which does not make sense, which is why they are sitting with stock they cannot get rid of, but advertising stock they do not have.
