Pathetic service and delays from Hollard Insurance

My dad who is a 71 year old pensioner took Hollard Policies offered via the Edcon Group. Since closing his account with Edcon, he has requested that Hollard give him a way to pay his premiums directly to Hollard. Email stating this was sent to ***, on the 10th Feb 2021, and was never responded to by Hollard. A 2nd email was sent to *** on the 12th Feb 2021 requesting a claims history on the policies, which to date has not been received. Follow up emails were sent a few days later, with no response. I then sent an email to ***, to which I was copied on an email from them to their colleagues requesting urgent assistance to resolve these matters. this was on the 17th Feb 2021. An email was then received from Candice Razaak, to say that the matter was being investigated, to which, nothing further has happened.
