Promotion item BUT no stock available

Hi, I have phoned practically every MTN store around Pretoria in order to upgrade my phone to the Samsung Galaxy S8 (which is not the problem) - but in the July 2017 edition of the Y'ello deals there is an offer to pay R130 p/month free and then receive the Samsung Gear 3 watch as part of the deal. Nobody has stock. MTN Direct does not have stock. MTN online does not have stock. Nobody knows when the stock will be arriving because there is apparently a "warehouse" problem. This is unacceptable and very pathetic. I have put my name on waiting lists.... but nobody can guarantee that the promotion will still be available. What now?
