Idea Cellular — idea cellular wrongly barring my number

Address:

560080

Dear sir,

Myself girish, recently 3 months back i ported my number from airtel to idea. And i got outgoing barred on date 30/08/2017 saying my previous operator bill is due.
But i paid my all dues of airtel on 10/08/2017.

Questions.

1) when i paid 3 weeks ago why my number got bared?
2) i tried to call customer care and their response was very pathetic and irresponsible.
3) before i barring i dint got hint.
4) after barring number even after 24 hr none of idea executive interacted with me.

This pathetic service i must say. I am regretting for switching.
