Worst Vodacom experience ever

I tried to do an upgrade online. Instead of doing an upgrade, Vodacom gave me a new contract. I contacted the call center. The upgrades department told me the new contract had been cancelled and organised my upgrade for me. After finally getting RAM to deliver my phone - they kept phoning the new contract number - they delivered 2 phones. I phoned the call center again, and again the agent told me that the new contract will be cancelled and that they will send RAM to come and fetch the additional phone. I had to go to our local Vodacom to do a sim swap - I wasn't informed that I will need a micro sim - when I queried this new contract and the fact that I didn't get my second sim card, the staff member told me they could not help me and that I must sort it out with the call center. Again I phoned the call center, finally getting through after getting cut off 3 times. Call center agent told me that they will send me sim to me asap. Nearly a month later I still have the additional phone waiting for Vodacom to come and fetch it, I still haven't received my sim card, and now I'm getting billed for this additional contract which I didn't even ask for. I have had my number with Vodacom since 2000 and have never had such hassle ever.
