Help

I got direct tv stream as a way to watch shows because I’m currently in a foreign country and wanted to watch things like the New Years Eve show but I quickly realized I couldn’t use direct tv stream in a country besides the US.  I’ve tried to cancel my free trial but I’m unable to chat online with a representative because the buttons to choose that option never work. I can’t call a representative either because once again, I’m in a foreign country and I don’t want to be charged with the international service fees.  I don’t know what to do because I don’t want to be charged for something I’m unable to use and unable to cancel. Please someone help me cancel it.
