Hey guys, I have been working on my online biz for the last 6 months and finally getting some cash rolling in. The biz provides services to clients and no product is shipped. In the beginning I used PayPal but 3 months ago they started holding my money so I switched to Authorize.net. Things were going good and I cleared away $700 in profit last month. Lo and behold, today I got three 'chargeback advice' from Authorize.net saying that the credit cards used were fraudulent and that they had taken $300 from my account. I banned the user from my site but the damage is done! They are asking for shipping information and AVS, but I never shipped a product so I guess I am screwed. I never had such issues with PayPal and am wondering if I should swallow my pride and go back to PayPal. Have you experienced something similar and how did you combat it?
