Sony India — Phone ringer got damage & company not giving replacement of it

Address:

Ghaziabad, Uttar Pradesh

Earlier i purchased Xperia Z2 but after using it for less than a week its battery got puffed so i had to returned it. After replacing it i bought xperia z3 on[protected], but after only 3 months, its ringer got burst & not giving proper sound, when i contacted sony service centre at R.N-Goel & Sons Pvt. Ltd. "523A, Ambedkar Road, Opp. Axis Bank, Ghaziabad-201001, Uttar Pradesh" +91-[protected] they told me that it will be send to sony centre and will be open forcefully by tools like knife & some other tools like that and company doesn't have a policy to give new phone to customer in exchange of that. Thus i am very much afraid that if the set will be opened in this manner then it will never be returned to its proper shape and will definitely get scratch mark on it, as i have spend 45000 Rs INR on it which is very huge amount for me and have to compromise with phone's body then it will be a very demotivating factor for me. I am facing problem with sony handset second time firstly my handset's battery puffed up and this time its ringer got damage. So kindly suggest me what should i do so that i can retain my faith in Sony. Thus kindly consider the seriousness of this issue and please do arrange to provide new handset in replacement of my only 3 months damaged phone.
