"Theft" from Vodacom - round nr 2

Here we go again..... October last year I listed a review highlighted incorrect charges on my contract. The free device, again, is not free anymore and I am being charged for it. A consultant, Lucien, helped last time and the charges were corrected for the next couple of months. NOTE that I was not refunded the extra charges. Let's see whether they will the decency this time around to fix this once and for all and whether I'll be refunded.
