You was supplied with the wrong headphones clearly.
Where did you buy the phone from? Apple? Second hand? Reseller?
If you go the apple website, iPhone 11, tech specs it says the following -
- iPhone with iOS 13
- EarPods with Lightning Connector
- Lightning to USB Cable
- USB Power Adapter
- Documentation
So it should come with headphones with a lightning connector, so you have clearly not got the right headphones
So clearly you did not do your research about what should be in the box, so clearly your initial rant is unjustified, as its a simple mistake that you got the wrong headphones.
As Apple have clearly intended to supply the correct headphones
