Sponsor has accused me of fraud.

Might be best to challenge it or it might be seen by them as an admission of guilt.
Either that or you might get trouble with other sponsors with the same billing.

I had that happen and the sponsor didn't tell me. I just went to log-in, and my log-in didn't work. After a lot of phone calls to various people (I called the info on their domain registration, silly me, I couldn't find anything on their site as far as contact info)

Come to find out, I had one sale and the person charged back, so since I had a 100% chargeback ratio, the cancelled me.

I spent quite a lot of time pulling links (back in the day before dragon links). I finally got a letter about a week later....gee if I hadn't of logged in, they would have gotten free traffic all that time.

I used to convert them really well, but they were starting to do bad anyways, but I thought it was piss poor customer service all around the way they handled it.
