WiFi Connection unstable resulting in mobile data getting depleted!!!

Does your apple iPhone 11 make you feel like it is just a banana!!!
Why are we paying for a product that is supposed to be one of the most advanced technologies around and suffer intolerable issues like dropping WiFi connection. My mobile data gets used up because the WiFi connection is so unstable. My notifications for WhatsApp read 50 and there’s only 10 texts received! Cellular connections are wavering. This is seriously the worst I have ever experienced with apple!!!
Why are we suffering this crap. Can I get a refund !!!?????
