Terrible experience with dynamic DNS from Telkom

First, I like Telkom. I'm happy with their fire internet.

I hope is is seen as constructive criticism. Please train your technical department on the workings of your dynamic DNS service. It's unacceptable that I had to explain it's nothing to do with the internet connection itself. Your dynamic DNS is incredibly unreliable and resolves to the previous IP address for days on end, defeating the purpose of such a service. All my sites are inaccessible and I have to wait for someone to eventually give me a static IP address. This is costing me money.

The customer portal give me access to only enable and disable the service. That doesn't get it to work again.

Please let me know what I can do in the mean time to get my sites back up.
