There are three Indianisms in this letter. They are:
- out of station
Instead one can say: out of town.
This is a very common word in India. Nothing wrong with it, but do keep in mind that outside India, people usually say please instead of kindly.
3. the same
This, like kindly, is a classic example of Indianism. Instead of ‘the same’ one can say: ‘it’.
And so, the full sentence reads:
Please resend it.
