I have been the user of noble K10u for around 3 years until lately one side of the earphone starts giving broken sound. I am sure I handle them with care all the time but it just happened. Disappointed at the short duration of such an expensive product, but I still trust it was my bad luck only as I don’t see other users reflecting this in the forums. I contacted Noble for a repair and immediately the next day they replied and offered me to purchase the new Encore or Katana universal at a discount instead. I accepted and paid immediately. Afterwards I have been asking for a tracking ID for delivery and no reply at all for 3-4 emails ever since I paid. I tried PM them in here as well and still nth. I was told to expect delivery within 2 weeks and now it is one month already. No earphone, no reply, I can feel that I am of no value as a customer after I paid them. All I was asking for is a tracking ID for delivery so that I can better arrange my time. Such a basic thing for online purchases I don’t see what is so difficult for a simple reply. I would be happy if they just tell me it is out of stock or they have too many orders to handle so they need longer time or whatsoever. Though I like their product, I am disappointed with their customer service I must say.
