Sentry Marketing basically refused to pay me

I did a shop in November, just one. I was paid $21 bucks for it. I got an email saying that the paper check option would be $2 or sign up with bill.com and they will pay me electronically thru there. I told them no. I would cancel my account and take the $2 penalty and bid them farewell. I was told then that they were going away from gigspot, and bill.com. and that i now had to sign up with dwolla.com to get my money. there is absolutely no way i will do that. I demanded a check and the guy David Agius, got real indignant with me. And told me that i had no option. Finally i pointed out that when i did the shop, a paper check was an option, and that legally had to honour that. he told me that it was a "special request " and would delay payment up to 30 more days.  I verified they had my address and moved about my life.

a few days ago i got another email saying to be sure to sign up with dwolla to make sure i get paid, i immediately responded to the negative and told them i expected a paper check.

now, today. i get an email from dwolla, saying that my $21 was sitting there waiting for me to collect it, after i sign up of course.  I immediately called and was rather rude to Pete over the phone and gave some choice words. I told him i was sorry, and i feel bad about it, but  this is crazy. i want my money, and i absolutely refuse to sign up for a third party company to get paid.

David Agius will be emailing me back, but conveniently enough, he wasn't in the office today.

I am still awaiting my one and only check. I will not be signing up with dwolla.com bill.com or anything. I offered that they could use my paypal, since it is an internationally well known company. he refused.
