Wireless Charger out of stock

I upgraded to the Samsung Galaxy S7 Edge on 14 March 2016 & was offered a free Wireless Charger, with the Consultant saying they are out of stock. To date I have made 3 calls to the store & each time they tell me they are still waiting & should be in next week. Its been over a month already & still no wireless charger.<br> I find this appalling as you cannot advertise a free wireless charger with the phone & not have anything in stock!
