Their system is separate from ours, so we do not have access to your account. When you setup your I-Pay account, you would have received a confirmation email from them with your login name and password. Sometimes this email can end up in you junk or spam. Can you try checking to see if you received this? Unfortunately, I can only provide you with you Pruvit login details.
Here is their phone number 1-866-844-5682, and here is their email address email@example.com.
