Revenue Provider

I received an email in my yahoo box as everyone does all the time. “To drive customer to your website”

It said in the email that I will get a free 50 $ if I sign up so I click on the link and thought that an advanced company as Yahoo would build in the promotion in the email link.
There was no other place to put the promotion code anyway so I thought ok I have 100 $ now. But no when my account was approved one day later there was only 50 $ in the account. I sent them several emails and told them that I am not going to use this service anymore if they do not give me the extra 50 $. The only way I could make them give in was when I told them I would make a chargeback on my credit card and then suddenly they gave me an extra 50 $.
