Trending @Wipro; Billing Issues wipro | Is this a scam

Folks, Scenario is I was tagged to a practice under support tagging with 100% billing from September 1st week till next year. Meanwhile they were suggesting some projects for me and I was waiting for the response from the project team. Suddenly they have reduced the billing from back dated . Reduced billing from back dated for one month and now they are saying your bench period is over. What to do in this scenario?
