Trying to refund or rebook my Lockdown flight

I am trying to find a way to rebook or refund my flight as my accommodation has been canceled due to the lock-down. No response to emails to ***. Call center not answering on ***. Not like I dont have enough stress simply hoping my business can survive this, now I have to put up with hours waiting for someone to answer. This is the service I expect from Telkom and thats why I no longer have any dealings with that failed organization!
