Forced into taking items not wanted, no feedback

I added a new contract to my existing account online. I took the Samsung Galaxy A5 with the free Gear 1. According to the online sales, all items requested were in stock. When someone called to finalize the sale, I was told I would need to wait 2 to 3 weeks for stock of the gear 1. I was told that I would not be able to have the phone sent to me until the gear 1 was in stock. I then requested to rather take the offer at a branch and was told I could not do that as the sale was already processed online and the only way to receive my phone would be to change my order to the armband and headset instead of the gear 1. Nothing like being bul**** into it! I then lodged a complaint and was told someone would get back to me, nothing. I queried the feedback and then received a call from someone from sales who said she would follow up the issue of the stock and come back to me. This was at the end of August. Since then I have had no feedback. Every time I request feedback I am told it has been escalated and someone will get back to me but nothing happens! I am disgusted! It has now become my fault that the system said there was stock when there wasn't and forcing me to take what I don't want
