Reliance Jio Infocomm — Jio sim lte volte facility and voice call facility is not working

Address:

Patna, Bihar, 680520

More than one week I am struggling with this complaint that my voice call and LTE Volte facility is not working. I took my Jio sim From Kerala for job purpose iam I am here in Patna, I won't be able to go to my state for the next 6 months, for rectifying this problem 3 times I mailed to [protected]@jio.com and 2 two times I went to the jio care in Patna
Telecommunications Service Provider · Shop No 2/13, Ground Floor, Braj Laxmi Mansion, Mauza Dhakanpura, Sahdeo Mahto Marg, Boring Road. So many times I called customer care in 199 through my friends Jio number, day before yesterday a customer care representative name Richard promised that I can get new sim card with the same number for that I went to the jio office in Patna today with my Aadhaar card and photo which they prescribed. But it was a hopeless experience for me the jio care staffs are not able to help me. Now I am disappointed the response from the customer care, I am wasting my time and money for this untrusted customer service.
Looking forward to see good result through this mail.
