I don't think that Digital River is a scammer, but its system is very bad. I do believe this company isn't customer friendly.
Our money was taken by this company for unwanted product. I had to be more careful about notifications from this company. However, the company's handling customer is very unskillful and unkind and I even felt they are lazy.
If you thought unauthorized money was taken, check if you receive any emails from digital river. You can find orders you made without conscientiously. It's very tricky.
