Advertising deals without having stock

I app**** for a new contract, on the Note 8 bundled with the Gear S3 Frontier, on the 8th November 2017 . I was told, by the store, that the Gear S3 Frontier was out of stock but a delivery was expected on the 14th November 2017. 14th I phoned the store to find out if the devices had arrived and was told it had not. 15th November I phoned 5 stores between my work and home (including the online store), only to hear the same story. No stock on the Gear S3 Frontier even though it is still advertised as a bundle online and in the booklets. Also no one can tell me when the stock will be available.
