Ignores emails - billing incorrect

Whenever I email Vodacom, they never respond, unless of course you want to take out a new product.... When you phone them, you're transferred to ten different people, because each one says it's not their department. Very **** service, and now I'm stuck with them for 2 years!<br> <br> They still haven't responded to this email sent on 13 January:<br> <br> \Hello<br> <br> I'm meant to have a data only line with Vodacom
