Taking my money and running

I recently sent in payment for my domain name and then received a bill for the domain name I had thought I sent payment in for. The invoice stated that I owed $70 and my account would be canceled if I didn't pay it. I called and talked to two people in customer service and was told that the initial $35 I sent was unrecoverable and it could not be applied to my main domain account. I don't use Raindance.com and will never use it. Either I made a mistake or you made a mistake because I double checked the invoice I sent in and it said Wilstrom.com. So now you have applied $35 to Raindance.com which should have just expired and you won't move the money to the account that I want kept active. What I understand is that this is standard practice to keep peoples money especially in this situation and to not transfer the funds to another account. I am not asking for a refund I am only asking for the money that was placed on the wrong account. The issue isn't so much the money but the ethics that this company is run under. I know of no business that could run by saying oh well you screwed up so your out or we made a mistake but it is policy not to fix our mistakes.
