2Talk has changed destination country bundle - South Africa no longer included

I've been with 2 Talk for a number of years and we make daily calls to South Africa. The $20 bundle was sufficient for us as it included calls to South Africa.

I've just noticed that South Africa is no longer included in the list of countries that qualify for in bundle minutes. They now charge $0.1 or $0..01 per minute I think (website isnt clear on pricing rate model, just has a value of 0.1)

Anyone have any insights for whats resulted in the change? I'm looking at other options too as $20 was the sweet spot for me.

On average 600-800 minutes per month for calls to SA.

Thanks
