Address:

110094

I purchased a Motorola Xplay handset on 24 October 2014. on 1 December 2014 a problem occurred in its speaker. I went to customer care service center on 3 December 2014. but on 4 December said its PCB is not working it will be replaced and right now PCB is not not available in stock. so it will take 10-15 days. after 15 days i went again they gave me same reply. i do not have any phone right now to communicate . even i also mailed many times to motorola customer support but they said we have shifted your your complaint to higher authorities. but no action taken till now. please help me regarding this. around 40 days have already been spent. i am attaching all copies of bills, emails etc.
