I had the motorola hs850 for nearly 10 months.I have had trouble with the headset heating up after using for 10 minutes. Even there was annoying background noise when the headset volume was increased. I stopped using this because of these issues for several months. Finally i decided to get a replacement set since i needed to use it.On july 26 2006 i placed a request for replacement and i was told that i would get it only after i send in the old one.I placed my credit card info on file with motorola so that they can ship it without me sending in the old headset first. After 1 week when i didnt get the headset i called CS and they coldly told me that they didnt place the order and would be doing it now. I asked them to expedite the shipping since it was their fault but the lady hung up on me saying i would get it few days.I waited for 1 more week and when i called again the rep said that no order was placed before as the rep forgot to place the order and they would place the order now. i was told coldy that i would get it after 1 week.I spoke to the supervisor and he said that he could not do anything and it would take time before i would get the headset.I think motorola deliberatly does this as they can avoid sending in headsets and people would tired of asking for replacing their defective headsets.Every time i called the reps say they get back in 1 min but take 5 minutes to 10 min before they talk to me again and it takes about 20 - 25 minutes to carry on a talk with them and place a request.My friend took a behind the ears plantronix headset and when it had to be replaced he just went to their website and gave his shipping address and his headset serial number and they shipped him a new replacement in 2 days and he leisurely sent the old headset back.i think its time to shift to better customer servicing manufacturers like plantronix who specialize in these products.
