Incredible Disconnection

I saw an advert about a promotion in a Sunday newspaper and visited the Centurion shop on Monday and asked the shop assistant if they have the 3g/LTE routers in stock. The sales assistant said that they only have portable USB routers/modems. I found it quite strange and mentioned that I saw the promotion in the newspaper. The sales assistant insisted that I must be mistaken and that the promotion must have been from Game. I left the shop dumbfounded and later returned with the advert. After I checked that the shop actually has the device I told the manager about the incident. His opinion was that I did not communicate clearly and it resulted in the misunderstanding. The Centurion shop should rename their shop to Incredible Disconnection.
