CMS / representative's name was Avis Claiming a I had a refund of a commission check due to me, but had to pay money before releasing it. California

I received a call on January 22 from (415)968-1710,  CA. I was told that I had over $3,000.00 in earnings from commissions on an online store that was set up for me and all I had to do was to pay the past due hosting/maintenance fee for one year, that was just $29.99 per month. My account was on hold due to my card declining over the past year resulting in me owing $359 in fees in order to get the over $3000 commission check released to me, it had to be paid.

I was told by the Rep: Avis that if I pay this by check or money order and send certified or with tracking, and call back with tracking number then they will release my commission check at that time. All they need is the tracking number that the $359 is on its way for them to release the over $3000 to me. She told me I would receive a call from the accounting department to verify everything that we discussed and confirm my email for the invoice to be sent to.  

Then I received another call from accounting it was a (866)248-3025 number, the man on the phone verified who I was and then asked me if I chose to continue with my website. I told him NO, he then said rudely, " do you enjoy wasting people's time?", I said no and then he over talked me as I was trying to tell him he was a scam and he said rudely again have fun with collections, and then hung up. I then still went with my gut feeling that this was a scam and researched the phone numbers and found that several other people had reported this.
