I would prefer to not contact them (Kisha and Yona) with my real identity. But I am assuming when we pay by PayPal, they get our information and then we will have to email them with our real personal email linked to PayPal. Is there any solution for this?
Not really.
Just an FYI - anytime you pay for anything the merchant will know your real identity (storefront readers more so than hotlines - the hotline company will know your info, not the reader).
You can create a fake email address or username or whatever, but when it comes down to payment, your name is attached to the transaction. The only way to get by this is to 1) Create an email with a random email name and 2) Use someone else's credit card/form of payment (you know, since we can't create fake credit card/bank accounts lol)....
Or maybe use your payment information and call with a different name? I don't know, but its probably important that the reader know your first name to connect to you properly...
