Aabaco Small Business Yahoo Domain hosting services and billing system rip-off Sunnyvale California

I had an account with Yahoo, now Aabaco, for domain hosting for the last 10 years.  Due to several factors, I decided to move to another provider.  My current billing period ends Dec 26, 2015. 

On Dec 8th, I made an online request through my new provider, GoDaddy, to transfer the domain.  GoDaddy indicated it would take 7 days. 

I received confirmation on Dec 13th that the transfer was completed away from Aabaco/Yahoo.  However, I noticed that Yahoo had submitted a charge for renewal on Dec 12th - four days after my transfer request and two weeks before the end of the renewal period.

I called an Aabaco customer service person today, and asked for them to reverse the charge.  After putting me on hold several times (either to do research or ask how to handle this), after about 30 minutes he came back and said the company refused to refund the money.  He did however cancel my current plan.

I told the customer service rep that I was prepared to escalate this by all means.  He just laughed at me and said, "do what you have to do".

This is a blatant ripoff.  I would have thought that Yahoo would operate with more integrity, and am hugely disappointed in them and their customer service.
