Rapidapi handles the payment processing and you are the third person in past 2 weeks that mentioned issue with credit card processing so there is definately something wrong on their end. There are two solutions:

1. RapidAPI support

Please submit a ticket through https://support.rapidapi.com/hc/en-us/requests/new

(choose public hub inquires from dropdown menu). They will create a manual invoice for you. Give it a day or so.

2. Direct Invoicing

Please reach out to us at info@specrom.com with the plan level you wish to subscribe and we will get you sorted by sending a paypal invoice and manually sending you the API credentials. Since it is Friday night here it will be atleast 1 day before we can send you an invoice.
