What's going on with my JBL Charge?

The last year I bought this product, the JBL Charge it's amazing and very useful!

But the last month, it started to habe some problems...

First of all, the Bluetooth conection doesn't work... I can't anymore conect my cell phone or any other thing by a Bluetooth conection.

Second, I don't why, but when I turn it on, like 20 seconds after it turns like "off" but still working, because I plug a AUX with my cell phone and I hear my songs, but it doesn't have the same quality that used to have...

Please I need your help! What can I do?

Where I can sent it to make it repair?

I'm from Paraguay, my name is Matias and I'm 18 actually...

Thanks you so much!
