user90047: Can someone pls help or explain to me what’s going on.

I put $60 in the Bitcoin atm so I can covert the $60 into bitcoin but only half of my money is in my wallet

Bitcoin ATMs charge fees for currency exchange. Sometimes they use jaw-dropping spreads on exchange rates. They are usually very expensive. Possibly more so for small amounts. Check your receipt.
If you think the machine made a mistake, contact the operator (don't contact the owner of the floorspace, they mostly just rent the floorspace they don't own the machine).

and it’s been 4 days

Waiting longer won't make any more BTC turn up. The transaction is done.

Footnote/Digression:
Bitcoin ATMs are not Automated Teller Machines (ATMs) they are automated currency exchanges, a different thing. Calling them BTMs is marginally better.
