Bests & Worsts Reviews from Amazon

I purchased this for my best friend. The sound could be as good as any bluetooth speaker. It also has great bass. The problem I have is Amazon continues to sell this when there is Zero customer service. When I say Zero I mean Zero. After 4 months the speaker would not hold a charge. I did not want my money back I only wanted to exchange this. Amazon would not warranty the product but said i had to contact the manufacturer. I did not have a problem doing this. I quit calling them after the 15th attempt and 1 months time. If you do not believe me call them no one will ever answer and when they tell you they are on the other line and will call back well I have now been waiting 4 months and my phone has not been ringing. I work for a huge corporate company who prides themselves on customer service. I am disappointed in Nyne and also Amazon for continuing to sell a product that does not have bad customer service they have no customer service. Don't believe me call yourself 805.751.4812. I do not bash companies but this is not right save yourself the headache buy another brand Like Acoustic Research who will stand behind their product. I would like a response from the company but still nothing.
