TrialPay, Inc. Took My Money and Ran! Mountain View, California

[October 5] I completed an offer with TrialPay and was informed that my item would arrive between October 19 and October 26.
[October 26] When my item didn't arrive, I contacted TrialPay customer support and informed them of the problem.
[October 28] TrialPay asked me to contact the company responsible for providing the free item. I sent an email to said company's support address.
[October 30] I informed TrialPay that the company they asked me to contact did not respond.  They told me that they would escalate the complaint and that if I did not hear from someone by November 3 that I should contact TrialPay customer support again.
[3 November] Having heard from no one, I contacted TrialPay to see what the next step was.
[5 November] Contacted TrialPay again, informing them that I still have a problem and that I don't appreciate being ignored.

A few things irk me here.  Cheif among them is that they put the responsibility of dealing with one of their (apparently delinquent) business partners on me.  I am not supposed to have to talk to three different company's customer supports when my dealings were initially only to be with one.

Also, it doesn't feel great to be dropped just because you're asking for what you were promised in the first place. They claim that they respond to emails between 24 and 48 hours of receipt. The fact that I haven't gotten a response to an email in so long tells me that I have been dropped as a customer.  They have no phone line for customer support, and they have stopped responding to email.
