Phone combo deal contract not honoured by Telkom

Telkom had a combo deal around October 2017 a Samsung S8+ & a Samsung Galaxy A3 2017 at a good price, I took up the contract on 16 October 2017 but at the time I only got the Samsung S8+ as they had to wait for stock to be delivered so I could get my other phone. Since then I have been sending countless emails and being told they still waiting for stock, at one stage I was told theres stock available so I went to the store on 17 March 2018 only to be dissapointed and told theres nothing in stock. I requested the store manager's contact details and was given an email to which I sent an email on 19 March 2018 & was told to wait for feedback as they would investigate. I waited and decided to send another email today only to get a shock of my life that the phone is no longer in stock and cannot be ordered anymore, I told them I only took up the contract because of the two phones I would get, I haven't recieved any response since then
