SMS charges too much

 I am a regular customer of Digicel PNG who always purchases the 60 SMS to text my friends and family. While on holiday, I am trying to get in touch with friends by using the 60 SMS promotion. However, it has been suspended as of Dec 24, 2015. Therefore my only choice is to use my credit to send messages. It is frustrating when 50t is charged for one texted message. I just topped up K3 and remained with K2.50 after a texted message was sent. How could I keep texting more messages with such charge? We are regular customers and will not go anywhere so please stop charging too much.
