Address:

Lucknow, Uttar Pradesh, 226001

My reliance landline phones 4 connection are not working and in dead condition from last 4 month and no one from reliance visited our site
I have complaint so many time on toll free no but every time they close the case next day. I have very bad experience regarding reliance landline.
Only call center people are citing they never no any thing also there is no escalation matrix to escalate the complain.
