Vodacom 'tickets'

I recently bought a whatsapp ticket and a social media ticket in the beginning of the month. Yesterday I notice my phone was extremely quiet. I saw I still had avaliable data. I decided to call the call centre for help, after a while holding she said they were having technical issues with regards to the tickets (so why are they still avaliable for purchase)I was also adviced not to purchase this product until further notice. I spent over 160 bucks on this ******* service and probably more as it was using my airtime instead of the data I had bought. The call centre lady credited me with R19 which doesn't nearly cover my loss in airtime. I am absolutely unhappy with Vodacom and if I was not tied into a contract I would switch service providers. Over priced and full of SH*T
