Zain/hr indexx/CCSNL d truth

Actually zain made use of hr indexx and ccsnl to recruit customer care executive. I have a very close friend that qualified and she is now working in zain call centre at abuja. Actually zain just opened their customer care office at abuja.
My friend was interviewed through phone and all other interviews bla bla by CCSNL here in abuja.
They finish their training not long
I culd remember during their training they asked them wether they have any friend that want to work with zain so she helped me fill my data in their data base.
CCSNL And HR INDEXX are seperate consulting but they are both recruitin 4 zain.
bUT my friend refuse 2tel me amount they earn per month.
I strongly believe its batch by batch they are doin
