Cannot subscribe to new DSTV Streaming Only packages

according to news on 2 December, one can now buy DSTV Streaming only packages on a month to month basis. I have now been trying to subscribe to one of the DSTV Streaming packages since Saturday 5 December... No luck.

Not sure if the complicating factor is that I had a DSTV dish many years ago, so I have an existing account number. Thus, when I log in, the system shows a window "Help us find you", and one need to supply the ID nr or Customer Nr. It then needs to confirm your identity via OTP. For the first week, the OTP function did not work so they at last fixed that yesterday. However, when I link my customer nr, the error message is "We can't find any packages for you to link to". If I skip the "Help us find you" function, you can go to "Get DSTV" and select a package, and try to buy it, error message appears "Unknown error finding customer ID Number ***x"

The Chat function on the site is **********. No context is retained, and every time when you chat, you start form scratch. The majority of the agents do not seem to know that streaming only packages are available, and keep on telling me that I do not have a decoder linked - I then need to refer them to their own website. Then the matter is "escalated to the technical team" and nothing is heard again. When I follow up a day later, we start from scratch again... The Facebook Messenger function is a little better because the earlier chats are retained, but every agent again would ask the same questions.

How can one contact a knowledgeable helpful person at DSTV who will really resolve this?
