As this is an account issue and it involves money and credit card details you will need to contact official support.Im sure you can understand that a public forum is not the place for such a support request.
You can send a mail to email@example.com
You could also use the ask a question part of the site which is found here http://www.metaboli.co.uk/faq/submit.do ... E907E1E3C4
You could try sending metad a pm to seee if it would help.Metad is generally the only official metaboli presence on these boards.However bear in mind there is no official presence on these boards from metaboli over the weekend
Also how long did you cancel the account before your next billing date was due?
When cancelling you need to give 8 days notice.In other words you need to cancel 8 days before your billing date.This is to ensure there is adequate time for both meta and your bank to stop the payment.
"Cancellation is carried out online by contacting Client Support. The cancellation must be carried out a minimum of 8 days before the subscription renewal date. This technical delay is necessary to ensure that the cancellation has taken effect prior to the bank taking payment for another monthly period of the Pack chosen by the User"
The above is taken from the terms and condition that you agreed to when signing up to the service and is available here.http://img.metaboli.fr/cga/uk/cga_lp.pdf
