HTC India — HTC 628 dual sim/performance not as per specification

Address:

Lucknow, Uttar Pradesh, 226022

I bought this hand set last year in july. I was using it with a single sim till i bought a jio lte sim last jan. Though the phone specifications are 4g/lte it does not recognize jio sim as lte instead it shows as 4g. Last month it's software started malfunctioning for which i contacted your service centre at lucknow. Where they formatted and installed new software. There they told me that this phone is not lte compliant and it is a hardware issue. When ever i connect to wi-fi the jio sim goes offline, neither i can receive nor call on this. Now for last two days jio sim going offline and connects only on restart. Please help me solve my problems. Thanks.
