If you come across Simpliworks again, I advise you to stay away from them. They will simply take your money without providing any worthwhile service.

1. I can't access Simpliworks. (Message shows "Email is invalid." It's deleted)

2. Have you resolved the errors? I manually removed all campaigns from both your dashboard and Amazon campaigns, but I was still being charged for campaigns that keep getting added repeatedly. Very annoying and wasted my money.
