I have sony walkman ipod, i brought from usa . It's really nice product . But last 3/4 months it's have some problem . It's not charge properly and not works .
Today i visit to sony care at kunj 58 alkapuri vadodara . For repair . But they says it's not repairs . It's directly replace . You need to show the bill . I have the online purchase receipt and bill . But they said it's already 5 years done . So they won't help me for replacement as well . It's just past 3 months to 5 year .
So what can we do as a customer .I am ready to pay for repair or pay for give chargers for replace as well but if customer purchase expensive and brand name product . Just belive as a good brand . Should i throw this product ? How customer can believe in big brand . Now what can i do with this walkman . They don't repair or not replace . What is the brand value for customer now ? There is no values of our bills it's just over 3 months . Even if customer request to pay for replacement . Which kind of service or ans getting at customer service center
