Reliance Communications — Converted to 4g, still not able to connect to hybrid mode

Address:

I have converted my dongle to 4g according to reliance customer care instruction and recharged it for 797 but still network shows high speed 1x. i have contacted so many times to customer care but no use. customer care is useless, now they are not even attending the call. why reliance is using these kind of cheap techniques to grab money from local people. guys stay away from this company. i am really fed up with this.
