I don't get calls from them. But then, they really don't have a whole lot in my area, either.
Also, I haven't had trouble being paid by them, when I have done jobs for them. Oh wait, yes I did, this last time in September... but I'm pretty sure that was the first time there was an issue. I got the email about checks sent, but mine never showed up in a reasonable time; I got a re-issued check about three or so weeks later. However, after responding to my initial email with a question to confirm my mailing address, I never heard another word from them despite multiple emails asking when/if I was going to get a replacement check. I just wish someone would've sent a quick response, even just a "We're taking care of it, your check will be re-issued on XX/XX." would've been fine by me.
Happiness is merely life's way of keeping you off-balance.
