How can I cancel my account?
From VoiceMailTel Wiki
To request cancellation of an account please make sure the invoices payments are up to date and there is no outstanding balance on your account.
If the abovementioned condition is fulfilled, to cancel an account simply send a cancelation email to sales@voicemailtel.com
The account will be canceled the same day (working day) when VoiceMailTel received your request and you won't be billed for any extra day.
We will be sorry to see you go. If you have a moment, please let us know why you are canceling so we can work to improve our service.
