ARE VODACOM SO DESPERATE?

I HAD MY CONTRACT ONE YEAR WHEN VODACOM SUDDENLY CHANGED MY CONTRACT RATE WITH INCREASES. I COMPLAINT BUT NOTHING WAS ACHIEVED. OK SO I VOWED TO TERMINATE ALL MY EXISTING CONTRACTS AS SOON AS THEIR EXPIRY DATE CAME UP. GAVE NOTICE TODAY ON MY ONE CONTRACT AS IT EXPRIES 29/04/2016, I HAVE AN SMS FROM THEM CONFIRMING THAT THIS WOULD BE MY UPGRADE DATE, KEPT THE SMS AND STILL HAVE IT. ALSO KEPT MY ORIGINAL TILL SLIP DATED 04/04/2014 WHEN I TOOK OUT THE CONTRACT. WHAT DOES VODACOM DO? THEY EMAILED ME AN EARLY CANCELLATION FEE QUOTE! ARE THESE PEOPLE FOR REAL? DO THEY REALIZE THAT I HAVE ALL ORIGINAL PAPERWORK. DO THEY REALLY WANT TO GO THERE? VODACOM I WILL SEE YOU IN COURT BUT I WILL NO LONGER PARTICIPATE IN YOUR *****ULANT ACTIVITIES. GUESS WHAT I AM STILL CANCELLING ANOTHER TWO CONTRACTS AND HAVE ALL MY ORIGINAL PAPERWORK FOR THAT TOO!!!
