Motorola Mobility — Not repairing the device

Address:

Haridwar, Uttarakhand, 247667

Hi, From last 56+ days I'm struggling with a Motorola service center for repairing my nexus 6 but they just make nonsense excuses and delaying it. I submit my device for repairing (audio normalizing+low battery backup and heat-up issue) on the 28th of September (Job Sheet Number IGT/MG/15/00186) after a long time on the 19th of November service center call me for collecting the device, but (they didn't fix the battery issue yet) after checking the device I found weird noise coming from the speaker and a huge dent on back side. So service center told me to wait for Monday 23rd of November and today on Monday 23rd November they say wait for 10-15 days for replacing the speaker assembly and again 10-15 days for replacing the back cover because Motorola replace the each part separately and I'm assuming another 10-15 days for the new battery also Motorola customer care telling me that my Job Sheet Number is closed. Now what? if we calculate the total days, which Motorola needed for repairing the device is 100+ Is that a joke or something else? Back side dent pic attached
