Samsung Galaxy S4 Issue

Hello,

(images at bottom showing problem)

I bought a pre-owned Samsung Galaxy S4 from my local AT&T Store about seven months ago, and never realized that I have had a problem since the moment I bought my phone.  I have always had issues with charging my phone, sometimes it would charge, others, I would have to fiddle with the charger until it would finally work, and now the issue is even worse.  My phone was at five percent a days use, and bought a new charger (I had lost my other charger), and the charger REFUSED TO CHARGE MY PHONE!!  I thought it must be the new charger not working, so I went, bought a different charger, and it STILL REFUSED TO CHARGE.  I finally decided to pop open the back cover, and take a look.  I pulled out my battery, and sure enough one of the battery connectors was broken.  I had never touched it before, so it just broke.  I hadn't dropped my phone, so there was no logical explanation for the physical damage.  To make something clear, I never knew of the connector being broken until this moment.  I finally found a way to make my phone charge.  I have to shut it down, and it will charge.  It takes HOURS.  It is not fast, and is very noisy.  The phone powers on, vibrates showing it is charging, loses connection, and shuts back down.  The phone will NOT charge when on, and when powered on still thinks a USB connector is plugged in.

I just got off the phone with an AT&T Customer Service representative.  He was very kind, and explained that he could not do anything about the phone.  I told him how I did not break the connector, and since I BOUGHT THE PRE-OWNED PHONE BROKEN FROM AT&T that they should help me out with the financial costs with replacement. (there was no yelling involved as some people may interpret from the all caps).  The representative gave me many options, all which cost's money, or to send it in to Samsung and wait four to six weeks.

Since the phone was returned from a previous customer, refurbished, and resold to me, I strongly believe that the previous owner knew about the problem, and stuffed back the battery connector into the port.  I have always thought that the connector was supposed to be shorter than the rest (farthest right on phone) and never realized how easy it was to push it in with a screw driver.  When it popped out on me, I pushed it back in, and it worked temporarily.  This paragraph is probably confusing, but my point simply is that I did not break the phone, yet AT&T will not help me out.

Right now I discovered another weird issue.  I shut down my phone with 14%, rebooted it, and now I have 25%.  This shows how broken the battery meter, and connectors are.

I looked at local cell repair shops, and they couldn't help me, so if you can... any advice is helpful.

Please let me know if you have any ideas on how to deal with this issue. 

Thanks,
