Level 3

$pay->paying = $request->paying += 500;

every time you refresh the page the $request->paying is back to the initial value. you should add the +500 to the $pay->paying

$oldPaying = $pay->paying;
$pay->paying = $oldPaying + 500;

Or take a look at the link that @sr57 sent. laravel has increment and decrement on models which you can use.
