Same thing happend to me like a month ago, phone nokia customer service. They forwarded me to the nokia care center in my town and they didnt ask for proof of purchase from me.

The local shop will be un able to fix the broken port and will have to send to nokia directly, any way it took like 2 months to get a brand new one because they had non in stock supposidly.

If it is contract mobile, phone the contract company they will replace or repair it. They should also give you a phone to tied u over till it comes back.
