Contract chaos

Using my last data to write this, as it has been depleted rapidly this month. Took a 5gig day, 5gig night contract for R199p/m with Vodacom in July '17 with the understanding that we can cancel within 14 days. After struggling a few days to find out where I can track my usage, the account stood at R475. Therefore we decided to cancel. Phoned 082111, was referred to ********** . Didn't get his name, but was promised collection of router. Did hear anything till R475 was deducted from our account. Phoned ********** again, sorry, 14 day reversal of contract no longer valid. Referred us to ********** . Spoke to Hope who dropped the call on us. Spoke to Patricia who promised collection and refund of our money. Reference number given. Wait 5-7 working days for collection. Nothing. Phoned again, spoke to Gugu. No record of the reference number. Will get back to us. I've never dealt with a company that made me use so many explosive words. So unfair that it's easy to take out a contract and so hard to get them to honour their agreement.
