Continuous poor service from Vodacom

I upgraded my contract online. RAM couriers never delivered the phone to the supp**** work address. Numerous enquiries to Vodacom resulted in them telling me to take up the matter with RAM myself. I eventually cancelled the online upgrade, on 18 Feb 2016; the cancellation was confirmed via SMS by Vodacom. Vodacom advised then that I could upgrade in any Vodacom store myself. I phoned Paddocks in Milnerton, and spoke to Erin; she confirmed that I still needed to cancel the online upgrade as this was still active. I was confused as this was supposedly done? I went to the store in Paddocks and Erin assisted in trying to cancel this with numerous calls to whomever at Vodacom. I am a Vodacom client now for15 years, but this is exceptionally poor service. If Vodacom is not sorting out their problems, this is not my problem.
