Iphone 4s won't charge after repair?

In the beginning (before I got it repaired) I noticed that my iphone 4s wasn't charging. I went to the Verizon store to see what the problem is but they said there was no water damage and I could go get it repaired. So they told me to try this repair place called Gameco. They man charged me $45 to troubleshoot my phone, he opened it up and said that my charging port was bad and needed to be replaced and he charged me $89. He fixed it in 2 days and called my friend to tell me that my phone was fixed but when I got to the place to pick it up me and the man tested it to charge and it wouldn't charge. He told me that it was charging before I came to pick it up. So after that I tried it at my home on my charger and it still wouldn't charge so I took it back to the place and he said that he will look at it again. It's been a week since I dropped it off again, I called him to check up on it and he told me that he still couldn't figure it out and he was still working on it. He also told me that it could be body damage but that's kind of impossible imo because I never dropped it. And I was just wondering if anyone knows what could be preventing my iphone from charging.

Why is the iPhone 5 more expensive than the iPhone 5C?

Well iPhone 5C is newer and had a little improvement (not much of a difference, I know) but why is it less expensive than iPhone 5?

They are still selling iPhone 5 here in our country I'm wondering why the price of 5C is lower than 5 even if it has sort of improvement.

How to unlock a verizon iPhone 4s?

So my friend gave me an iPhone because he wasn't using it. He had verizon though and I have AT&T. I went to the AT&T store and they said once I unlock it, they can transfer a sim that would fit the iPhone(currently have an android that doesn't have a sim that would fit) I'm trying to find a way to unlock my phone without having another sim or anything. Is there a way I can unlock it through a jailbroken source?
