Huawei India — Phone not getting repaired which is submitted under warranty

Address:

Dhanbad, Jharkhand, 826001

I have submitted my phone Huawei Honor 6( model - honor 6 H60-L04, IMEI No. [protected]) at the huawei service center (The S.D. Communication, Garia, Kolkata) on 28th October, 2015. Huawei has a policy of repairing the phone within 15 days from the day of submission. Now it is going to be a month. When i call at the huawei customer care they say that your phone will be repaired soon and give me a complaint number and say that their technical team will contact us within 48 hrs. This thing they have told me several times (more than 7 to 8 times) but the thing is that they never call us back, all the time they say only that they will contact us within 48 hrs. When i say them to transfer my call to the higher authority then their higher authority never pick up the call. when i visited the service center in kolkata they say that it will take more than one month to get the phone repaired. when i called the customer care and have them talk with the service center people then the service center people told them that it is the server issue and then the customer care people told me that they will tell me in two days to what to do of the phone but again they didn't call back. The service center people again told me that they will take more than one month again to get the phone repaired. Moreover, the service center people hasn't generated the invoice number of the phone yet and without generating invoice number the phone can't be repaired. i have also send huawei a mail at service.hw.[protected]@huawei.com with my invoice copy attached but my mail hasn't been acknowledged by them yet. i want my phone repaired as soon as possible and please also provide me the date/time before which my phone gets repaired and that time should be in days not in month. My contact no. is [protected]/[protected]. i am attaching my invoice and snapshot of the mail i have sent to them. i am totally exhausted by the customer support of huawei and it's service.
