Vodacom is *****ing my data!!

<p>I am so frustrated with Vodacom! In March my data was constantly running out despite my nearly daily top ups. I received 2 GBs on 1 April with the start of the new month and within 3 days that had run out! Feeling completely defeated, I went to Vodacom in Nicolway and purchased a 10 GB wifi bundle. WITHIN 3 DAYS this has run out! How is that even possible? I don't download movies or music or anything other than emails! How is it possible for ONE PERSON to devour 12 GBs of data within 6 DAYS? Vodacom, Please tell me! This is unacceptable! I have been a loyal customer for over 10 years so I hope to have this situation resloved as soon as possible! </p>
