I received this email after checking this topic. I am on the old billing record.
Dear <<my name>>,
Thank you for your kind support and co operation towards
ComputingHost.com . You have helped us grow with your continued support.
As you have been a regular and good member, we offer you a chance to shift
your account to a new billing system. We at ComputingHost are constantly
making sure that you receive the service that you deserve

It has been a long time since we set up our new billing system and now we
have decided to transfer all of the clients to the new billing system.
Your Account Username : <<removed>>
The reason for this is :-
* The development of the old billing system software has stopped.
* There are still many unknown bugs in the system.
* Inability to choose payment gateways when making a payment.
* No proper system for easy upgrades.
* No detailed records of payments made.
Hence to prevent any more inconvenience to you, our customer
ComputingHost has decided to move your accounts to the new billing system.

Please reply to this email when you are ready for the shift and your account
will be shifted to the new billing system. If you have any doubts queries or
suggestions then you can mail us at sales {at} computinghost [dot]com .
Also :-
* 1. None of your site's data will be harmed for this is only a shift of the billing
record and not your site.
* Your billing subscription will be canceled and a new one will be set up when
you pay your next invoice.
* If there is any pending amount.. the invoices will be adjusted so that you
are billed on the right date.
* It will be done only when you have sent us an email.
Regards,
