Dotzot — product not delivered and no response

I have ordered one bluetooth speaker from harman audio order id[protected]. It was shipped via dotzot 10 days back but there is no sign of delivery yet. It was promised to be delivered in 5-7! Days and it has been 20 days now. Tracking id[protected]. I am starting to think that both harman and dotzot are cheating customers. I am going to go to consumer court as i have all the proofs and invoice.
