Vodacom Fibre Deals Misleading

Just go Fibre installed by Vodacom in Eastvale for atheist R650 deal With free installation with an invoice declaring this, yet, over the past two months they have deducted R735 and today, R749. The guy at the Vodacom shop, gave us a lousy explanation for the previous deduction and ensured us that today, R650 will be deducted agreed, and then I wake up to this? This is really misleading and costly, Vodacom has no truth you know, I can’t continue like this.
