Still the saga continues....

My contract was upgraded on 9 Jan. Vodacom messed up after they confirmed my upgrade in writing and confirmed the delivery address also in writing to me. I never got the phone and Vodacom cancelled the upgrade behind my back without informing me. Then on the 1st Feb they accused me falsely of owing R150. For an upgrade fee of an upgrade that was never done. Furthermore they also without informing me, just discontinued my BIS service. The very unhelpful operator at 111 told me there was an upgrade done on 21 Jan. They cancelled the BIS and that Vodacom can cancel it whenever they want.... I agreed to a 24 month contract paying a fixed fee monthly that according to that contract INCLUDES free BIS! Why is that free BIS cancelled 4 months before the end of my contract? Is it because I complained too much for Vodacom? Because of my hellopeter reports? WHY? They now want me to pay R58 per month EXTRA to have BIS. This just does not match up? If my free bis as per 24 month contract is taken away, I must then pay R58 per month less, isn't it? Can I get a copy of my contract where it says that the free BIS would only be for 20 months? I find it shocking, and repelling what happened to me
