MWB *****ulant Debit orders for 3 years and your support team denies this.

MWEB has allowed a *****ulant debit order to be taken off my account for 3 years + We only hire an MWEB email address but when I called the call centre, they informed that I am also paying for a domain name www.goodlifelife.co.za . I have never regitsted this. When I was asked to write a formal complaint to ***, they told me that I am not paying for the domain. But why is my bank account being debited by R159 every month and your call centre confirmed that I have been paying for a domain and an email address? Your call centre picks it up but your team at docs@mweb can't pick it up. I have followed up 4 times now but I am getting nowehere. How can your client details be so different from one department to another? I need a refund and this to be resolved urgently.
