Telkom is useless!

So Telkom recently changed their billing methods and now I cant pay my bill. Also I can't call them as I need airtime (I use minutes on my MTN account). Now that I'm trying to sort this out as I created an account on my registered email there are no payable accounts to select. Trying to retrieve a different username (I suspect it might be my cell number) the site that telkom suggests (https://customerportal.telkomsa.net/portal/password/forgotUsername.jsf) you cant select the service as their website is broken.

How on earth can you change billing methods and make it so hard to pay your bill.

As a kicker I loaded god damn airtime and the billing department is now closed and you waist your damn airtime by having to wait for the stupid irrelevant info the reader gives you.
