Bose SoundLink Mini Speaker

I purchased Bose Sound link mini bluetooth speaker at great expense. At first it worked fine but all of a sudden the red charging light keeps on blinking and I cannot turn on the speaker. Tried contacting Bose but have not received any reply or assistance to either fix up my speaker or replace it. I have been a HUGE Bose fan and got my entire home fitted out with a Bose sound system and numerous headphones etc. Now I really regret wasting money on this expensive speaker where a cheaper on would have sufficed
