@sajhaa, they do have notifications 2-3 months ahead. I'm a service provider and I deal with at least 3 registrars and they all manage to send me renewal notice ahead of time.
First of all Nepal's web service providers like Yomari, dreams&ideas,etc .. these guys are bunch of losers and thugs who sells pirated movies, sells stolen third-party scripts to their customers and so and so. Imagine, if these are the guys handling or providing services for news network or sites like ekantipur, what can you expect? These drunk bastards wouldn't even care but act last minute of craziness.

So, I've more than 1 hundred domains and I handle them in time. Your concept of not being able to manage them because of different renewal time in a year is quite unbelievable.

As someone wrote, this is extreme example of negligence.

but I don't care, I never read their site :D
