I know it might sound stupid...But anyway bear with me...As a noob I started with 7Search, POF and few others. This is about 7Search.
I was not able to make any kind of profit so far...I paused the campaigns long time back...but a balance of approx $22 is there....so far my data goes like this....
June 01, 2013 - June 30, 2013:
Paid Survey - Broke Even
Finance - Slight Loss
Giveaway - Slight Loss
Please help by:
*Enlightening me with the niche so that I can break even with the remaining balance.
*If not at least suggest me with the niche to test and go forward with other paid PPC.
Thanks in advance....cheers... 
Contact them and ask to have subid blocking enabled. Once you block out some of the lower quality traffic you may be able to get that break even campaign in the green.
Allright...acting as u've said....
Thanks a ton
Cheers...
