1. It's clear on the promotion "10% cashback on all your weekly tennis bet net losses!" That's mean your network incorm (In-lose situation or not). Example, you're betting in "Tennis Match" with Total 5x Games with 2,000$ Wagering. You also lose some bet, but based on your net income of the week you deposit (In) 500$ and (Out) 530$ even you're losing some match. You're not qualified for the promotion, because your network is not on losing situation.

2. You have been warned, do not opened a multiple ticket with a same topic you're asking. Off course they're gonna to warn you, since you keep asking the same question while team already gave you some answer.
