Cannot finish data bundle and cannot transfer money

<p>My 2GB recurring data bundle was almost depleted so I decided to load money to buy a new recurring bundle at R1399. Vodacom did not allow me to buy a new bundle because the current bundle was not depleted (at 200kb). With this data was now being charged at R2/mb which is extremely expensive. I then tried to move the money to another number so that I could force deplete the 200kb on my account. I could only transfer R1185 to another number and not the full amount. I have now tried to revert the R1185 from the other number and vodacom keeps telling me that I don't have airtime even though I have R1185 on the other number. What is going on?!!?!</p>
