Converted to Prepaid and now number is suspended

I had a contract with Vodacom that expired and I requested to change it to prepaid. I ahd to reuqest this 3 times via the call center and eventually resorted to twitter, and was finally helped by the team there. However, they moved my number to prepaid and with that my account ended up in a pre-legal status. Even though the agent promised that a credit would be passed on my account I then had to go to a store, which I did and they told me to pay the outstanding balance - which was for Sept, and which i actually didn't have to pay. I wanted my phone to work, so paid the amount It has now been 9 days, without being able to use my phone. My number is still suspended. I have now been to the store again on 2 occasions and have sent many messages to the team on twitter, but nothing This is really shocking! Can you please just unblock my number and get my phone working again?
