Finally refunding of Deep Pruple tickets has begun in Kathmandu. Some of them have been refunded and some are on the waiting list. The refunding is being provided from their Durbar Marg office behind police booth.
If you have not claimed for your tickets then grab it as soon as possible. Its quite unusual that they have not provided any information on their websites (which is closed now) or on their facebook page.
Anyhow, claim for your tickets before they run out of cash.
