Unable to get assistance from Discovery website, phone lines and agent chat via whatsapp

I tried to log into my discovery profile on the website and it wants a OTP to pass the 2-step authentication, this was never the case in the past. The OTP does not come through after numerous attempts. I called *** but the machine keeps saying "sorry, the dialed number is not in service" I attempted the chat with Sandile Ndamase and he/she was of no help as he/she refer me to call the same number. Who created this authentication on my profile? I do not want it.
