Query: Was great for 7 months then it stopped working.

I loved my iBall. The sound quality and range was excellent for a relatively modest price. I say "loved" because after 7 months the product stopped working. Now I have to pay to ship the item back to the manufacturer in order to get it fixed or receive a replacement.To add insult to injury I found the customer service representative I spoke to on the phone rather rude and disinterested in my problem. He rattled through the warranty-return-address so quickly I could not write it down even after asking him repeatedly to speak more slowly. He demanded my contact information rather than asking politely for it without the use please's, thank you's and any apologies.I would recommend purchasing from a brand with higher quality and better customer service.
