Dissapointment always No Stock

Good day

I have received your special offer catalogue and decided on the Colima 15 piece bed set, product code : 808215 on Queen Size, to my dissapointment no stock.... whenever you have and advertise specials you dont have stock, not even an option for ordering and placing on back stock, how can you advertise if you dont have the product ? I have checked other items too which you advertise..... No Stock ! Totally dissapointed
