I do know that Check n Go is a member of the CFSA (
Community Financial Services Association of America), see the link below for a list of members:
http://www.cfsa.net/MemberList.aspx
I can't see Quik Cash listed there but that doesn't mean they aren't members, one way to find out is to find their website and look around to see if there is something that states they are, or you could call them and ask. Anyway, members of the CFSA offer an EPP (Extended payment plan), you have to request it because they won't tell you about it, and, from what I have read from other members Check n Go is notorious for claiming they don't offer it, so, you will need to PRESS the point to them, print out a copy of the member list at the link above which shows them listed, then print out a copy of the "Industries Best Practices", the link is below, highlight number 11 which clearly shows they MUST allow you the EPP if they are members of the CFSA (and they are), don't let them tell you no, make it clear that you are requesting an EPP.
