Southern Railway — Shortage of tickets in ticket counter

Sir
I am traveling from cherukara to ernakulam south twice in a week,
The passengers are suffering shortage of ticket to ernakulam south/ north for a month, from cherukara railway station, it's very risky to take two times tickets for a one sided journey, or more expensive than actual ticket, also there is chance to lose train if i'm talking two times!! It's ok if only one or two days. But one month is really inconvenience to us!!
Hopes your immediate response to this complaint,
Kindly your attention to solve this problem

Thank you
Best regards
