Huawei — Mobile Handset not returned

I gave my Huawei Honor 6 mobile for Service on Aug 31, 2015 at Sri Vinayaka Electronics(authorized service center), HYD. At the beginning the service center guys said they’ll be giving my mobile back in couple of days. Later when I called the service center guys they were not answering the calls, they were putting the call on hold and later they used to cut the call. On persistent calling they said my mobile was sent to B’lore for service. When I called Huawei ([protected]) they said wait for 15days from the date of giving mobile for service. Now when I call them (Huawei) on the 15th day regarding my mobile they’re saying they still need time to provide the status of my mobile. Without my phone there’s lots of work pending. Huawei people gave me a ticket number saying they still need 48 hours for providing me status of the mobile and not to provide my mobile(ticket number[protected]. Require immediate action and my mobile back. Thanks.
