Vodacom are *****. Appalling service delivery.

I was contacted by a Vodacom representative to upgrade. After advising this person that I travel for work he agreed that the courier will arrange delivery at a time and place convenient to me. This turned out to be utter nonsense. Lie 1. The courier unable to arrange a suitable delivery arrangement, referred me back to the Vodacom consultant who assured me that the transaction is cancelled and that I will be refunded. Again no shred of truth. Lie 2&3. Trust and faith in call centres shattered I visited the store in an effort to resolve. I was turned away with a number to phone to resolve. I did, no response, I then sent a mail to Vodacom who in turn confirmed that the the cancellation was processed. Yet again, a complete lie, nr 4. Upon visiting the store again today, 3 months since the start of the ordeal, I was met with shrugs, the store manager confirmed that not even at director level can they resolve and that there is no platform for in store complaints? A dubious practise at best and utterly useless of course. No time frame could be provided for any possible resolution and the absolute best that can be done is to send a mail!!? No apologies were ever offered. What now?
