I bought minecraft but got a minecraft fake

After months of playing the game with my friends compute I finally bought it on minecraft.net. instead of getting the real minecraft I got a minecraft fake. I selected minecraft for windows 10. This is clearly a minecraft fake for the following reasons

The chat is at the top left instead of the bottom left

The menu looks completely different

F3 doesnt work

I cant make a furnace minecart

View bobbing is completely broken

Commands are completely outdated. /execute is like 1.12, /effect is like 1.12, there is no /locatebiome 

There is an offhand slot but its completely useless. I cant out items in it.

Arrows simply dont stay inside the player

Sounds are completepy outdated. I thought it is 1.18.

It says 1.18 even though it is 1.7 since I cannot go into spectator mode

I cannot find spectral arrows

There is no luck effect

Skeleton ai is outdated

I cannot see my effects when I open the inventory

/seed doesnt work

I dont want to play a minecraft fake like this one. This is unplayable. Please give me the REAL MINECRAFT!!!!!!!
