starter kit came with micro usb and doesn't match arduino uno

kikon:
my arduino starter kit came with a usb cable with a micro usb on the end that doesn't match the female plug on the arduino uno board. Why did this happed?

Most likely they put in the wrong thing. They need to give you a cable with a USB-B male connector (male rectangular cross-section one) on one end, and a regular USB-A male connector on the other end.
