My iPod 4G won't charge when i plug it in, and won't connect to my computer! Please help!!

Please help me! I've tried 3 other cords and tried wiggling the cord around and I've blown into the iPod to get any dust out and nothings changed. This has been going on for about 2 months and no one has the right answers, and I was supposed to get a new cord delivered from Apple but the messed up my order :/ If you have a solution, please share it with me, I need help now! 😢
