Line international call issues

I have used Line to call landline or mobile in my home country for the past few years without problems.

Now in the past 2 or 3 weeks whenever i want to make a call I got the message that the network was overloaded.

Then today when I call a landline, I first get a voice message from the operator in my country that the number I dialed is not in service, though it is my parents number and I called it from the contact list.

The following calls I hear the phone at the other side rings, my credit starts running which is not normal, but nobody answers the phone.

I use Skype and the phone is answered right away and I'm informed that no previous calls were received.

I retry another 3 times using Line and each time same result as earlier that the credit start running, call is not picked up, and at home no phone is ringing.

Has anyone else experienced similar issues with Line recently?
