Charger port not working? Acer Aspire 7560

Onala

Recently it seems my laptop's charger port has completely stopped working. It suddenly stopped even holding the charger and won't charge at all even if I hold the charger. I've tried multiple chargers on it but it's the same thing with all of them even though they work fine in a friend's laptop (who has the same one). I went to the repair link on the main site but since I'm a month past when my warranty ran out it tells me to go back. Who do I contact to go about getting this repaired and does anyone have an estimate on how much it will cost?

 

Thanks in advance.
