Data Disappeared and Useless Call centre

I bought a 7 day 10 gig data bundle on the 21st Feb that was due to expire on the 28th Feb at 23:59 as per the confirmation SMS that I recieved from Vodacom.I woke up on the 28th and all my data had expired.I called the Call centre and a call was logged and I was told that my data would be refunded.I called back again today and was told that the system made an error in sending me the message.The call centre and the alleged Superviser Nombuso made me feel like an idiot by counting like a toddler and saying that that data was due to expire on the 27th.Im absolutely disgusted with the way this matter was handled because neither of them took responsibility or bothered to listen to what was my issue.So just like that it was blamed on a system error that had nothing to do with me
