No response after 3 emails

Sent an email to info@miway one month ago requesting cancellation of my insurance policy , to ensure no further debits are made on my account and to advise me that this has been effected. Three weeks later , no reply and lo and behold , a debit is processed against my account on 28th August. 2nd email sent on the 28th August requesting a refund of the debit and asking for the courtesy of a reply . 3rd email sent today after once again getting no response from Miway. This is shocking service from a company to its customers.
