Yes, if you get paid in 2 months you are very lucky.  I've done their work for probably 10 years or so, and a couple of years ago, payments just stopped.  The only way I'd get my money was to cut them off.  Then when they'd send me an order I'd have to remind them that they were cut off, they'd send me a check and we'd start all over again!  Worked for a while, but now they've owed me since last summer.  I'm tired of playing games just to get paid for work I've done.
