Charged for data never received/****** data

<p>I purchased 1GB in June. A few days later my line was upgraded and all my data and minutes(over 600)was gone including the GB I had just purchased. I phoned the call center and they apologized stating that even the purchased data would be now null en void and that this should have been explained to me! After my upgraded had been affected I phoned to asked if an extra 500mb could be added every month to my contract as I already receive 500mbs,I have just received my bill and I have now been charged twice for 1GB! The 1GB that was effectively ****** and 1GB that I only received 500mbs of! This is disgusting Vodacom you have ****** 1.5GB from me and are happy to debit me for 2GB.</p>
