Levi's India — colour discharge of denim

I purchased one denim on sale from levi's store indiranagar bangalore.
The first time i wore the jeans, it started discharging color and stained my new white shoes, which were much more expensive than the denim. It also spoilt the tshirt i wore it with.

Being a new denim, i ignored at first but it started damaging every piece of clothing i used it with. When i tried to contact the store, they said jeans will always behave like this, you may wash and it will be fine. When i washed it was discharging colour as if i have put additional colour. Any normal cloth would stop discharging after two washes. But this pair did not. Also the shoes that were spoilt do not return to its original state after numerous washes and i cant wear it any more. The denim still leaves colour in the same amount. When i took the jeans to store they said it will go for quality check and then only they will do anything. For another 10 days they did not update. Only when i called they said its rejected and there is no quality issue.

When i asked for the proof and reason they said there is no written proof and the corporate office only communicated over phone.in a register it was written that it is not approved. How can i believe if it actually went for quality check? They ask me to write to levi's corporate office regarding my issue.

Its been 5 days and they have not provided any resolution and when i call they ask me to check with customer care and disconnect the call. Later they refuse to talk.
Its been a month that i am struggling for a pair of jeans. I want a refund of that jeans asap.
