Broken USB slots on Advent 9115 notebook?

My Advent 9115 notebook has 4 usb slots all of which are broken. The one on the side and 2 at the back have collapsed completley which means I can't use them at all and the other one at the back has an extremley loose connection which means I have to fiddle around with the USB for ages until my laptop picks it up. Is there anyway I could fix this? If so how much would it roughly cost?
