HTC — Phone service delayed

Address:

Bangalore, Karnataka

My name is Syed Mahmood Tahla, a resident of Bangalore. I purchased a HTC 820 phone from Sangeetha stores on February 6 2015. Since my phone's headphone jack was not working, I decided to give my phone for service to the HTC Service center in Whitefield on the 20th of May to sort out the issues pertaining on my phone. They mentioned to me that they will return the repaired phone back to me within a maximum period of 2 weeks. It has been more than 31 days, and they have failed to return the phone or inform to me about the status of my phone's service. The phone was also under warranty. I am deeply disappointed with their service and I expect them to return my repaired phone by 23rd of May or I will take up this matter in legal ways.
