Consumer Redressal

i submitted my device in the service center on the 17th and still haven't got it. i tried calling so many times but no body picks. first they said they will give my device in ten days. then they said they will return it by this week, when i called today they said it will take three four days more. moreover the person i talked to was so rude and offensive. first of all they don't reply to calls and emails and then when they do they are rude and do not resolve my problem properly. i have been facing so many problem without my device. they say each time that they don't have the part, it is unbelievable that such a big company like motorola does not even have parts and it takes more than 15 days to resolve a minor problem. they should actually replace my fone as my fone was just two months old and it started having problems. i mean if they cant resolve it they should replace my fone positively.
