Dear sir & madam,
The enclosed boat rockerz 255 bluetooth headset which i purchased on (Amazon) october -17, 2019 is one side speaker not working properly. As it is still covered by the original manufacturer warranty. I requested that u repair or replace it. My sales invoice & warranty number are enclosed. Please ship the repaired or replaced iteam to me at the address on this letterhead.
Thank you for your prompt attention...
