Message text:
Sir,
We have received a notice from your card service stating that there
was a chargeback made by the owner of the card that you paid for
your account with. This is a very serious matter.
I have deducted the amount of the chargeback, GBP 102.10, from your
account and added our standard fee of GBP 23.95 as well. (You can
see your payment details in attachment.)
If there was some mistake, please let us know immediately so that we
can get this situation resolved. We ask that you have the chargeback
removed as soon as possible, as our account has already been debited
for the amount in question.
If you would prefer to make your payment using a new payment
method that would be fine as well (you can use a different credit
card or you may send a money order payable to Cihost).
This is a time sensitive issue and must be resolved promptly at the
request of the card service. Please email the billing team using the
Web Administration Panel with information about how you are going
to deal with this situation.
I thank you for your time and hope to hear from you
soon.
See your payment details in attachment.
Sincerely,
