Question about Meta Rift S

I ordered for the second time after I cancelled the order last month because the glasses were postponed again every day for more than a month without knowing the exact date. Now I ordered the glasses again the other day because you are fooling me again with your information, why did it say delivery in approx. 3 days and suddenly after you buy them it's weeks again. Are the glasses still available at Digitec this year or do we have to get them somewhere else?
