Lost in warranty land at sumsung

<p>i bought a battery for my mobile phone at sumsung rosebank exactly six months back. about a month ago it started giving me problems. not lasting more than 9 hours on a single charge. i took it back n was told that the warranty is 6 months, but i had left my proof of payment in my dorm room. came back the following day and was told that i was overcharging the battery and the store policy is that no batteries are exchanged after six months although the warranty is 6 months!!</p> <p>i have also checked on the sumsung website, and it says that warranty is for 12 months on an original sumsung battery.</p> <p>the salesman that assisted me just giggled n did not pay much attention to my case.</p> <p>i still have the faulty battery and can't use my phone for more than 9 hours.</p>
