Unable to top up ADSL data......again !

<p>Go through the whole rigmarole to buy ADSL data from Telkom, only to be told ( at the last step ) : Not authorised. Tried with 2 credit cards. Phoned help line. Told me to phone sales. Yes, they are closed. That means no data until tomorrow when Sales opens and I can talk to them. Then maybe I will be able to purchase data, or maybe not. Previously they could not even help me at the physical office in the mall. Why is it so difficult ?? And why always Telkom ?? I am so fed up with this company. </p>
