UPGRADE NOT WHAT WAS PROMISED

I recently upgraded my cellphone contract and received my new handset in July - all was well and the data and airtime was what was promised. Come 01 July and I get the correct airtime but the data is incorrect and they only deduct R100 from my bank, the same amount was deducted 25 July.<br> I sent an email to the Customer care email address on their website on 13 July - NO RESPONSE. I resent the email on 20 July and received a voicemail of a call I missed from Virgin promising to call me back - NOBODY called me back. I resent the email twice on 24 July as I was highly irritated by then, and still nobody called me to get this resolved<br> Very bad service - this is not the first time - it happens every time I upgrade that my package is captured incorrectly and this is the second time I upgrade
