MTN Mobile App.

I am using the MTN mobile app, and every time I login I am asked to download the new version of the app, as the current version is no longer supported. Problem is I am out of the country for an extended period and when I try and download it I am told that "this application is not available in your country". I have been trying to get an answer from MTN for the past four weeks (***) as to how I can get around this, and all they do is refer me to their website. Honestly MTN I know my way around the internet. This is obviously not the run of the mill question, hence the reason why they cant answer me. I am also told that there is no other way to access my account information, I only have one access point and that is the mobile app on my phone, which is now unsupported. Is there someone Senior at MTN who can answer my question.
