vodacom *****

I loaded 500mb of data and in 5mins I received a message that said I had 40mbs of data remaining. when I called the contact centre regarding this I was told that the transaction does not reflect on their side (I thought well this makes sense); then the agent proceeded to say that perhaps the money was not taken from my account or my bank had not allocated the funds!!!!! this was not a card purchase it was concluded on a banking app, secondly I had advised the agent numerous times that the money was deducted and my balance had gone down. This is theft and clearly Vodacom agents are trained to not assist customers but rather to help the company rip us off!!!! R100 is a lot of money to give away to Vodacom!! and they do not appear to want to help in rectifying the situation!!!!! I am very upset about this I've been a loyal customer for decades this sort of service puts me off
