Nightmare called Vodacom contract

I have been trying to execute early termination of my Vodacom contract since the 5th September 2017 when I paid the quote they issued for early termination. Well, it's 17th Sept and: NOTHING! First Vodacom Cape Gate branch says they can email the paperwork for cancellation. 1 week later I receive an email that they are not allowed to do this on the customers behalf since 31 August 2017, but on the 5th Sept 2017 they mailed it, am I missing something , are the staff not clued up? Don't make a promise to a customer and underdeliver (1week later!). When I emailed the store I received a snotty response that they didn't know about this change (implemented 31 Aug 2017) and "you'll have to email them yourself ..." No apology, no sorry for the inconvenience of our error. Now I am struggling to cancel my contract after emailing Rententions dept at Vodacom. I am told I was supposed to receive a reference number, which I haven't received. The fact that Vodacom Cape Gate branch emailed my documents may also be the reason for this delay as told by the Vodacom call centre agent. I'll never take out a contract with Vodacom and I've advised my friends and family to rather opt for the prepaid route. Thanks Vodacom Cape Gate branch for messing things up for me and being arrogant and nonchalant about it.
