Uninor / Telenor — Company not Providing duplicate sim card

Address:

Dehradun, Uttarakhand, 249201

I bought a telenor sim about 4 years ago, i lost it about 8 to 9 days ago. I went to telenor office to collect duplicate of my sim, they checked my id details, but the id on which my sim is working didn't match to mine. They said the sim will be given only when the same person and same id will be available.
When i bought my sim i gave my id to the retailer, but he exchanged my id with someone's. I didn't know anything about this because there wasn't any sim card verification process 4 years ago.
I was using this sim card from last 4 years. In this mess, my responsibility was to give my id to the retailer but he did something wrong due to which i m getting suffered.
This is not a customer's fault that the id was exchanged.
I said to the telenor executive that i am providing all the details about my call details, my recharges, but they are not agreeing to give me the duplicate sim card.
I was using this sim card since four years, and this is my permanent number.
My telenor number is [protected]
Please help me regarding all this.
