NO FOLLOW UP AS PROMISED BY CONSULTANT

after my last review i got a call very quickly from Vodacom advising that they would sort my problem out. guess what a week later i am still waiting to hear from Theo the consultant that called me and promised to resolve this issue. I have now also been billed incorrectly and my problem with my night owl data not resolved. i HAVE BEEN BILLED MY OLD PREMIUM INSTEAD OF MY NEW AMOUNT. I have sent numerous emails requesting for Theo to call me and guess what nothing to date. i am tired of calling and emailing and getting no response. VODACOM'S SERVICE STINKS.
