How long does it take to settle the commission after a phone call from the sales department?

Within a week.

It is difficult to give a positive answer to this question about time, because it depends on the actual situation of the developer. Under normal circumstances, it will usually be one week to half a week after completion. The developer pays the other party monthly to settle all the accounts, but sometimes because the developer's funds may not be in place, a temporary IOU will be issued and the account will be settled after the developer has enough money. If the developer has been unwilling to settle the commission, then I think as a service provider, it can protect its own interests through the court and must not let its own interests be damaged.
