This is the third time I have submitted a complaint and todate I have not received even an acknowledgement.. I bought Bluetooth wireless headphones (A58040) last year and within months the charging port became detached and dropped into the body of the earphones thus rendering the earphones useless. I bought AKAI thinking that being Japanese they would be good quality. Prior to the problem they were used on average once or twice a week so I am very disappointed. that they are now useless. Please have the courtesy of replying, trust me I will not let the matter rest.
