Harman India — service not being provided for jbl flip 4 which is under warranty

Address:	Pune, Maharashtra, 411057
Website:	in.jbl.com

I have a jbl flip 4 (Around 8 months old). All of sudden battery backup reduced to maximum 20 mins on full charge.
I raised a complaint with customer service on 23rd november 2018, and was informed that they will pick up the product for repairing with in 24-48 hours. I again called on 27th as the committed period was over and no one showed up. Again they escalated the matter and its been almost a week and still no sign of help from their side.

Complaint numbers: mh_c[protected], mh_e[protected], mh_e[protected], mh-e[protected].

I hope to get resolution on this platform.
