There's an implied warranty of merchantability/fitness for a particular purpose which basically translates to this: they sold you a phone and the main function of the phone is to talk via voice. If the speakers do not work, then there's nothing you can really use the phone for, especially not what it is designed to do. Therefore, a warranty in writing is likely not needed. I'm assuming this phone could range from $20 to $600 or more, so depending on how much you've spent, you may want to consult with an attorney to seek help getting reimbursed. What manufacturer is it? As far as time to respond, a reasonable amount of time should be granted- I'd say 2 weeks max. Since there is no warranty in writing, thus no "full warranty" I don't think the Magnuson Moss act is relevant.

I agree. Then if no response, find out if the retailer will give you a new one. If not, send them a demand letter, and one to the manufacturer. Then sue the seller in small claims.
