Bad customer service

I requested a document to be picked up and delivered to a government department as they needed a tracking number. I struggled with the address in the online booking as it auto predicts, finally I entered the address but is was in a different suburb and different postal code - same city. I tried to chat online but there is a message saying they are very busy, finally they answered, I stated my case - no reply and an hour later I shut down the window. The document was collected and delivered. I asked using the online "contact us" function for a proof of delivery, I had to do this a few times as it reset, finally I managed to send it and a message pops up for a split second - eventually I recorded the screen to get the pop up - "message sent" No reply, its been days now. RAM management have identified that the staff is overloaded they should employ more people, there is nothing worse than trying to get hold of a company. If RAM cannot manage all the customer portals close them down and only have one that is efficient! I need the POD, and also perhaps put a copy on your website so that future customers have easy access.
