I believe the problem is with you.
You were being lined up for interviews you said, this just means that you are being endorsed to an account... and yet you declined. And now, you are saying that you don't have any work yet.
First of all, you have no right to decline. If you decline, a Show-Cause Memo can be issued against you for 'insubordination'. You were endorsed to a new account because the old one ceased. This scenario is not even a Constructive Dismissal case as stated in the title.
This is the correct process in the BPO scene. If an account closes, the agent cannot decline a new account if he/she is endorsed to it. If an agent can't be endorsed to any account within 6 months, he/she shall be redundated and the corresponding separation pays will be given.
