Ehi Guys,
I run a lot of traffic on Fb, but I have the Bills at only 750$.
This means that Facebook is bidding me and asking me to pay too many times per day!!!
Is there a way to increase my Bill limit?
I also have problems related to my campaigns. Since I run a lot of them, recently I have reached the Facebook Ad's limit. 
Again, Can I improve this limit somehow??
Thanks
Where are you based in?
I am based in Europe! Receiving Billings from Facebook Ireland!
You can possibly contact an fb rep and ask for a line of credit, but usually this is reserved for people who have spent a minimum of high 6 digits.
