Consumer Redressal

I have ordered Humidifier on 9th November and the estimated date of delivery was 13th Nov,(order no.1255008NP51854996) and we are on 28th Nov and there is no update on my order, when I check the tracking details it says the order is in Bangalore and the date shown is 15th Nov and there is no update after that, the call centre is for ever busy there is no one to answer your call or take the complaint. There is no courtesy to reply on the n number of mails which I sent. With great difficulty when I got through the customer care number they told it would be delivered on 26th Nov but I have not yet received it. This is my worst experience till date with any of the E-commerce site, please understand I wanted to buy humidifier for my 1 year old son thinking it would give him some relief and there is absolutely no sense of responsibility you have and this would be my last purchase from you. Can anyone from the firstcry team have the spine to call me and let me know when would the order be del
