The approval is done by the local area exchange people that too by the technical backend team.
About my experience which was kind of similar, as last i had created a service order request for plan change through cc since selfcare portal in north doesn't allow plan change. The service order started reflecting immediately but didn't get processed for 4-5 days. After multiple calls got to know that the backend team in the main exchange in city (mine is a rural exchange which doesn't handle any kind of activation) was supposed to confirm it by giving me a call about the plan change.
These lazy people don't even check their system to see if there are any pending service order requests created through different modes. Best is to give a call to local sde to get hold of right person if it doesn't get processed on its own.
