Sony — Delay in replacement of phone handset after approval of replacement.

Address:

Nashik, Maharashtra

I had submitted phone handset (SONY Xperia ZL ) in Nashik Sony authorised service centre (Yash electronics). Due to not working of ringer loudspeaker & over heating of handset. I submitted handset on 1 Feb 14, they said phone will be replaced within 8 days, but till today 19 Feb 14 there is no proper response from Service centre & Sony customer care. Ticket id- [protected] job no- W[protected] Submission Date on Sony centre - 1 Feb 14. I am very fed up & frustrated by following them. Suggest me what can I do next.
