Reliance Jio Infocomm — internet speed and bad calling network

Address:

Amravati, Maharashtra, 444602

Jio means high speed connection
Everyone have a jio sims but why it is so slow:, lte4g but speed is only 400 or 500 or 700 kbps

They say about it speed is 150mbps we can read article of 4g its speed support 150mbps
Instead of 150 mb it can give 50 mbps but not
On 500 to 700 kbps and sometimes speed is 150 to 100 kbps why
I did not want 150 mbps, instead of it i just want 3 to 5 mbps is sufficiant for me only and calling is ultimately # if we want to call we have to 3 to 5 times for get connection to that person
Evry time we call its say buzy, shutdown, not reach able,
After 3 to 5 times we get connection to that partyicular person
And is so good i say hello front person say...,.;.;,.; whats that yaar!!!
