No refills for model 60 cylinders

I wanted to refil my 4 m9del 60 cylinders. I visited 7 retailers who do refils. All with the new refill bottle. I exchanged one to see if it will fit. No it doesn't. I contacted sodasteam, just to hear they are not planning to discontinue the pink model 60 bottle. When asking to assist where I can find some. No answer. How do you after 6 years having this machine just make a new one. Now ehat do I do??? Sodastream is just making money and wasting ours
