Telkom LTE top-up bundle not loaded and have to wait after weekend.

Ran out of data om Friday 18 October and purchased a top-up bundle around 19h00. Kids wanted to watch cartoons on Netflix. I waited patiently for my internet to work again but nothing happened. On Saturday 19 October around 16h00, I called technical support and was told the bundle didn't go through. It will be escalated to the manager who isn't working for the weekend. He "might or might not" read his e-mails. I asked if I have to wait till Monday for my bundle to kick in and spend the whole weekend without data, the agent told me that it "might or might not" happen. Therefore no data for the weekend. What is the use of a top-up service if you can't use it on a weekend? I already received my invoice and my credit card billed for it. This is unacceptable.
