New I Don't Have Access To Contact List To Make Calls

[maferbos]

When I open the telephone application to try to make a phone call, I get a message error and I can't use the mobile. I have reported the bug but I don't get any answer or solution.
The mobile only have two weeks, is it in warranty? How can I return it? Where can I go to repair the mobile?

I haven't installed anything, I am using the mobile with the software I received.
The MIUI version is 7.2.4.0.0 (MAACNDB) over android 6.0 MRA58k

I resolved the problem deleting the MI account.
