RCS Terrible customer service

I've been trying to close my Edgars account which is paid from the 17/12/2020.I was told to send ID copy with 3 signatures to their ***** department which I did and there was no response. When I called them they now telling me to go to the store so that the store can call them to remove the block from the account in order for it to be closed. The service is terrible,their agent either don't know their internal process or they just don't care about their customers and their agent don't even call customers back when when the phone call cut off so which means you'll need to start the conversation with new agent everytime the phone call get cut off. Edcon used give it's customers far much better service than this useless RCS Group.
