Hi @M488, welcome to our forum and I'm sorry to hear that your Xperia M4 Aqua is in need of repairs.
@alexdon has translated your post to English, since this is an English only forum. Please post your replies in English or use a translator service and we will do our best to help you.
As this is a Global forum and service routines may differ between markets, I would recommend that you get in touch with your Local support team and they will arrange a repair for you or give you information on where authorized service centres are located in your region/market.
I hope that helps!
