Pathetic company!!!

I called in earlier to cancel my contract- the contract ends at the end of April. I was told last week to call today and give notice- which I did. I was then forced (like I was forced last week too) to keep my contract!!! The consultants DO NOT LISTEN to what you say!!! They go on and on and on about various options to keep there and to take a new phone!!! They are very annoying!!! LISTEN TO WHAT YOUR CUSTOMER WANTS!!! I was being forced to take data and airtime over and over and I told her- I DON'T NEED EITHER!!! I have wifi and another phone to dial with! Finally I got answers. BUT THEN- I got a call from Vodacom Upgrades- WHICH I REJECTED. A few minutes later I get an sms saying that a quote has been generated on my profile and vetting has been approved- I APPROVED NO SUCH THING!!!! I WANT OUT VODACOM, YOU CONTINUOUSLY INCREASE CONTRACT TARIFFS AND ANOTHER INCREASE IS DUE IN APRIL- I DON'T WANT YOU ANYMORE- GET THE PICTURE PLEASE!!!!! Yes, I will keep my number and yes, I will add airtime to keep it active but, if you are going to be this stubborn- take my number too! I will just buy a prepaid sim!!!!! I also got sms's about a 50 minute voice bundle- WHAT IS THIS THAT WAS ACTIVATED????
