Bose India — Soundsports wireless sent for replacement did not receive back it's been almost 3 months

I have bought a soundsports earbuds from Amazon and when I had open the box or started the product I found out that the left earpiece did not work. So I tried informing the Bose service center for replacement of the product and they took the product from me for replacement and told me that we will recive the product within 5-6 days. Since then the service of the Bose company has been so worst that they are not answering my calls nor replying to mail and by chance if they answer they will tell we with get our product within 15 days 10 days etc. it’s been completely 3 months that the service center people are making such drama.
I’ll give a 0 rating for the service they are providing
Bose is such a huge name but they failed to keep their services worst service ever provided by Bose
No customer satisfaction
I will wait 15 days more if I did not get my product
I will raise a consumer complaint against Bose
