HTC India — htc 828 dual sim 32gb complaint about my mobile lost

Address:

Gwalior, Madhya Pradesh, 474001

Dear sir/madam
I gave my htc phone for repaired as it was getting switch off automatically and charging problem. I have given my mobile for repair at ahuja mobile service centre at danik bhaskar press bhaskarlane jayendraganj lashkar gwalior m. P. On 23.09.2017. Which was a authorized service centre or collection centre for htc, the address was given by htc customer care. They took my device on 23/09/17 and they told to contact me on 27/09/17 and they called and i got response that your phone has battery issue and after my confirmation battery has been ordered and replaced..! I went on 6th november 2017 and the response was they have not yet received the device and it will take 6 days..! And when i called on 13th november the response was the device has not yet reached and they don’t have any idea that when it will reach..! And then after i again visited service center again on 31st november 2017 they gave me same response that they have no idea who much time it will take… is this the response which they give to their customers?? Although i had called more than 10-20 times, but customer care people were very irresponsible, they promised me to go to look inot this matter and delivered my mobile with in 4 days. But i couldn’t received my device yet. Later they said they lost mobile parcel and it is not traceable around 25days. They promised me for replacement with new handset or refund the mobile amount. Couple of time spoken to supervisor also but that also went in vein. Till today i have not received my device. My ticket number is [protected].
Kindly you do take a responsibility and return my mobile immediately else i will take an legal action on htc india and will contact media also for giving horrible service like above.
