Failure to Respond

I have an ongoing issue where I am unable to make payments using the online portal. This was addressed in the past and the problem has now re-presented itself. I have logged several tickets with no response. I have tried to call the Billing Department only to give up holding on after 20 Min. I have attempted using the Facebook Messenger option only to be promised I will be called back and not receive the phone call.

It is such a pity that such a big company has such a poor attitude towards customer service
