Insurance Confirmation

On the 19th June I received a phone call as well as a sms to request confirmation of my comprehensive insurance for my vehicle. I immediately responded by getting the required confirmation from my insurance company, and send it to Wesbank by email on the 35th June. Today 1st of July I received another mail and sms notification advising me that Wesbank Insurance were unable to get hold of me, and that they are going to add limited insurance cover to my finance,until they receive this confirmation. When trying to phone them, I held on for 20 minutes without getting in touch with anyone. Is anyone even checking the mailbox that the insurance confirmation gets sent to. I see I am not the only client complaining about this today
