You should have been sent an email from your Company RingGo Corporate Administrator if you are a registered RingGo Corporate user.
If you have lost this email, or are not sure who your RingGo Corporate Administrator is, you can always check if you are a registered RingGo Corporate user by calling the RingGo service from your usual business phone. When testing, select the authorised vehicle, your zone, duration, and then attempt to make payment. If you are immediately offered RingGo Corporate as a payment option, the vehicle selected and phone number called from are configured for Corporate use.
If you are asked for credit or debit card details then unfortunately the vehicle or phone number are not configured for RingGo Corporate payments. You should refer any queries to your RingGo Corporate Administrator or employer in the first instance.
