Aabaco Yahoo Small Business Horrible! Nationwide

I've been extremely happy for the last ~15 years with Yahoo and then they dump my account to this horrible company. They wouldn't show my billing information on the site and redirected me to Yahoo Small Biz, which redirected me to Aabaco. It was a never ending circle. I didn't want to stay with Yahoo because I found a cheaper solution for what I was using their services. Aabaco provided NO advanced notice that they were about to charge my credit card. It wasn't until I received a fraud alert that I found out about it. They made me jump through ridiculous verification hoops in order to cancel the account, including 8 digits of the credit card they charged, that I don't use regularly and don't have access to. The claimed that it was their policy to verify the credit card and claimed that there was no way to verify the account without it, but less than 2 weeks ago, the pulled up my account and verified me without it. I was told to call the credit card company to get the 8 digits of my credit card. The last time I checked banks don't give out account numbers, partial or full. He claimed this is standard and banks do it all the time. Of course, the people that I dealt with had the standard thick accent that comes with customer service these days. RIDICULOUS!
