you are a lucky guy since you got refund from them. I called them many times regarding the issue, they said, "alright we cannot do anything for the card that you've already used up but we will certainly add minutes on your next purchase". Hoping that they are going to add minutes on my next purchase, I kept shopping card from their website. nothing  happened, so again i called them and explained the situation, "sorry for not taking care of you this time but we will definitely add minutes on your next purchase" is what they replied, noting my name down. I purchased another card and checked if i am really going to get all those previously lost minutes...but again nothing. I asked them for refund, but they again said we are going to add minutes in the next purchase.

man, I am here sharing with you guys all my bad moments with himtel because i was sucked up very badly.
