unable to purchase ad-hoc Data bundle

I ran out of data on my Smart75 package with Altech Autopage (Vodacom) and am unable to buy a simple ad-hoc data bundle. After waiting on the line for over 30 mins to their call centre number (***), I contacted the Victoria Centre branch in PMB. They gave me a recurring monthly data bundle (after I said I only want Ad-hoc) which I used up. I now have to contact Altech myself on the 30th to cancel the recurring bundle.<br> <br> After using up the recurring bundle I asked for an ad-hoc bundle at the branch. This was last week Friday and I am still waiting for a response - with no data on my phone which I need!<br> <br> I cannot understand how difficult it is for Altech to arrange their system for me to buy an ad-hoc data bundle.<br> <br>
