Being ignored by a claims manager will leave you with a big financial problem

I have been for two months now since December trying to communicate with claims agent Collen Baloyi who has ignored all of my emails. Despite me finally getting ahold of him on the phone last week. By luck when I called the call centre he picked up the phone and when I asked him why he did not respond to my emails, he said he couldn't find them. I asked him to email so I could forward my messages again and when he mailed me I directly responded to the exact email address which have been ignored now for two weeks. The reason I have been so desperately trying to get hold of Collen is that when I lodged my claim (Claim No ***) for hail damage, my car was taken to Renew-IT in Sandton. They have their own policy of repairing cars with 10 days but repairs to my car took a month. I contacted Renew-IT when my 10 day car hire with AVIS was ending to find out what was taking so long, they said I must contact DISCOVERY to extend my car rental period with AVIS so they complete repairs. I made multiple calls to discovery and could not get an agent, then I emailed Collen who had initially emailed me with my claim number. Collen ignored my emails and after three days had lapsed for car hire, I called again and a new agent managed to make arrange the extension. Renew- IT took 28 days to fix my car and I called AVIS to come and collect theirs. They delayed for two days despite us setting a time for collection. Eventually they arrived to collect the car. I received an sms from AVIS requesting R3 000 for scratches to the rental car, which I had reported immediately on collection. I was happy to pay this and made several calls to their Direct Billing office to pay for damages. I then got a letter of Demand on Monday for R5 000 for repairs. The additional costs were for extended car hire - This extended period is either the 3 days in which Collen Baloyi ignored my emails and did not arrange an extension, or the two day period where AVIS delayed to collect their car. I forwarded the letter of demand to Collen asking him to sort out this billing matter, I received an email from him requesting my claim number (which he has) but, sent it again. In the email where I sent him my claim number, I highlighted that it was unacceptable that he has been ignoring my emails since December and that the matter needs to be sorted out as soon as possible because AVIS requires payment within 7 days. It is no surprise that Collen has ignored this email too. I am at my wits end trying to communicate with Collen to sort out my bill, which I have made an active effort to pay by making numerous calls to AVIS direct billing, but when I was billed an extra R2 000 and requested assistance from my claim manager Collen Baloyi there has been continuous ignoring of my emails. This has been the most disappointing experience I have had with discovery, having been a client 5 years. And not just the issue of paying AVIS for extended days but also trying to deal with Renew-IT for damages they made to my car while it was being serviced. This information was also emailed to Collen and also been ignored.
