Woodland — Shoe sole come out

I had bought a woodland shoe for price Rs.10000/- from GEL Church complex main road ranchi showroom of woodland. After few days shoe sole starting coming out . I went to the store and they said that they will repair the shoe .
After few days they call me that this shoe cannot be repaired and they returned it to me.
My concern is that showroom had not sent the shoe to repair to the factory inspite they tried to patch it by themself, which makes the shoe even worst and now i cant wear that shoe. The showroom person is saying that they couldnt do anything for that.
What can i do now?
