Boltt - Headphones with manufacturing defect

Order #*****
*) I read wonderful reviews on Amazon for the Boltt Bluetooth Headphones. Later, I found that these are paid or fake reviews. Boltt actually invites YouTubers or influencers to promote the headphones in a way that it generates a lot of interest & momentum leading to innocent consumers getting tricked into a purchase. On their website, they have a separate section for collaborating with YouTubers.
*) So I paid Rs. **** & directly purchased the headphones from their site & to my utter horror, these were defective from the word go. There's something not fixed inside left earcup & the sound is getting worse. Let's say if you are walking in your own house, listening to a song, while you walk, there will be a constant jerking sound from the left earcup. If one slightly tilts head, the same jerking sound of something freely moving inside the left earcup will come & keep repeating untill you feel like throwing this shitty pair of headphones into the dustbin.
*) In my naivety, I went to their site, filled up the complaint form & no complaint number was generated. It's just a google form.
*) Their customer care number is invalid.
*) They don't reply to complaints posted on social media.
*) They have one email id & they have been sending bot replies since three weeks. First week, they refused. And then they started sending copy paste bot replies.
*) Their policy clearly talks of immediate refund in case of a manufacturing defect although it's clear that they don't have a customer care so the policy as well as warranty is useless & a waste of one's time & energy.
*) My only mistake was buying the headphones in a hurry without doing a check although with the misleading & fake/ paid reviews on Amazon, there was no reason to doubt. They are cheating & doing it in a very smart way, by building up a fake or paid four stars & above rating on a reputed site like that of Amazon. And by recruiting one or two YouTubers who are masters in faking a good review for a disgusting cheap headphone.
*) If you do a search on 'Fire boltt blast ****', then you will find that a lot of people have reported this manufacturing defect of something moving inside left ear cup & consequently giving out an irritating sound while one is attending a call or listening to a song. Basically, the purpose of using a headphone gets defeated. Aksham Chawla is one gentleman who had this same issue. A question is posted on Amazon & with a guy responding in yes to this known manufacturing defect in Boltt.

Please take action against these fraudsters & first of all, pls refund my hard earned Rs. **** ASAP so that i can purchase some other genuine headphones instead of this crap.
