Wesbank loads insurance without customer consent

Wesbank asked for confirmation of insurance details which has been sent to them. Wesbank then sent a mail advising that they will load insurance on the vehicle as they have not received any insurance confirmation. Tried getting hold of them on the number they have given and no answer, called numerous times and still no answer.

Please check your systems for the confirmation of insurance that I sent you. You cannot just load an insurance premium without my acknowledgment.

Eagerly waiting for your call or some assistance.
