Sony Xperia — sim detection issue

Address:

New Delhi, Delhi

Sir, myself vijay kumar. sir my brother bought a sony xperia t3 on 4th may 2015 from "Sheeba Tel Pvt Ltd" late evening. he presented me the mobile . i dont had micro sim therefore i went to the "Sheeba Tel Pvt Ltd" and asked them to cut the sim and insert inside mobile. The concerned person in shop don't know how to insert but they tried using pin one by one. At last third or fourth person inserted the sim. I happily came back but from that day only the networks were not good. I live in tihar jail staff quarters where networks are weak, therefor i thought that its ok. but the the problem started increasing. On 11th july 2015 i completely lost my networks, so went to the sony service centre janak puri. They checked and said that one of the sim tray pin is damaged, therefore it does not come under warranty. I told them the whole story so they said they forward my request and call me on 15 july 2015 but i have not received any call. Sir i want to ask if you have authorized a store to sell your product then how can i expect that they do not know how to insert sim. You can check the cctv footage of the store if you don't believe me. Sir they are selling your product so its your responsibility to care care of there knowledge about the product . when i asked the service centre officials about the approximate estimate of repair they said around 8000. Don't you think that its a mental harassment that for a mobile of 15000 rupees you are asking 8000 rupees for such minor repair. I want to ask why should i pay a single rupee without any mistake. Sir i am just a student who is not earning, so its more than just mental harassment. Sir please help me out because i am very disturbed because of your services. i am also sending you the service center receipt, the written request i had given in service center and the bill of mobile . And i again request you to check the cctv if you don't believe.
