Unable to contact Midrand License Department

I completed all my documents to renew my drivers license in December 2021 and I have not heard from them to collect my new license, I have tried to call them and the person who "answers the phone" just cuts the call as soon as it starts ringing. I have sent the sms to 33214 as per the website and this comes back as failed on numerous tries. Do I just have to go there to find out what is going on?
