SARS PATHETIC AND APPALLING CONTACT CENTRE !!!!!!

I have been trying to get ahold of Sars for the longest time to fill my business tax- i have been made aware that i need to fill via email as i could not do it online as i have come across a error to do it and unfortunately could not go into a branch to fill the return - so i tried calling to get this done before the due date - Eventually requested a callback because one waits for more than hour just to get assisted then i requested the callback option - someone eventually calls me back today then i answered the call but then nobody was talking to me but yet the call was answered and then the staff is laughing in the background and chatting not aware that im still on the line - trying to get assisted to do this Return as it is their job - This is absolutely not okay for someone that runs a business and not having enough time as it is - to still deal with this pathetic call Centre service - I WANT SOMEONE TO CALL ME SO I CAN GET THIS RETURN FILLED SO THAT I AM ABLE TO GET MY BEE CERTIFICATE , i am not able to apply for a tender now because of this Sloppy Service i think many people are getting from this Government institution!!!!!!!!
