Vodacom - Customer retention not a priority

Very gutted about the service I've received from vodacom. I recently discovered that I've been de*****ed by vodacom. Everytime I take an airtime advance it gets deducted when I recharge and also gets added to my monthly bill. I brought this to their attention only to be assisted by a very arrogant agent who clearly had no intention of retaining me as a customer.

I've been with this service provider for almost 10 years, I think it is time I cut ties. This where the loyalty ends, but before then I want my money back, the money deducted ********ly from my account
