NEVER HAS STOCK

After battling for more than 2 weeks to have my cellphone contract upgraded, when I finally get it right, you don't have the phone is stock that I want. Why is this advertised (new brochure came out today 20/05), if NONE of your stores have this in stock??? After saying numerous times that I want the blue Huawei P30 lite, (as its a gift), you STILL insist I take a black one!
