I’ve got my Magsafe melting and fraying. I try to claim that defect to Apple Authorized Reseller, but it can’t! Magsafe price is $79. In my country, the price up to IDR 900.000. I didn’t have enough money to buy new charger. So, I cut the cable and reconnect it. Then, give some super glue and wrap the cable connection using Metal Audio Jack Connector. It works!
