Charging port lose and won't charge

view story

http://androidforums.com – My charging port is lose and I have to hold the charger or move it around and sometimes wrap it around the phone. How can I fix this? My sprint rep told me that sprint will not fix it cuz they can not sauder. I was thinking about getting the powermat recever door but unsure if it will work. I already have an extra battery and charger to have 2 batteries. I really just needing a cheap and easy fix until after January so I can upgrade. (General)
