i agree with james. specially weekly billing. but even with weekly terms dealing with mediator is real tough job.
Mediators existance we can’t rule out. they won’t lets you to contact the main client or main client may not be willing to contact call center directly.You won’t find any listing of such mediators abroad or in India to whome anybody can rely.
I hope atleast there must be some control/varification by govt if the mediator is indian.
Genuine mediators plays a very important role and if they charging some amount then thats their bread.
my conclusion is existance of mediators is must and its very helpfull for both clients and call centers. But there must be some regulatory body who can assure both clients and call center.
LETS HOPE SOMETHING WILL COMEUP POSITIVE in this direction with time.
