Yet another frustrating ordeal with Vodacom

I do not understand why all communication with Vodacom, always has to be so difficult and frustrating, the customer service is shockingly bad! I have been trying to get my contract cancelled since the 5th of February, after numerous calls and emails, I still haven't had any luck. I have done everything according to Vodacom's rules and regulations - I've sent an email for the 30 day notification of cancellation and STILL waiting for Customer Care to assist me by sending my cancellation confirmation. Please I ask of you to PLEASE reply on your emails!! Vodacom as per my emails, you are NOT going to be able to get hold of me on my cell phone number, I'm not in SA - you will have to communicate with me via email. I don't know why it always has to end up putting a complaint on here to get you to respond.
