VODACOM FIBRE

I have used vodacom for many years and I was appalled by their current tactic to take money from me. I have had home fibre for 50mbps and for the past 2 months a fee for 100mbps has been deducted from my bank. I only realized this when I went to review the invoices and noticed a change. I have tried to communicate my frustrations with the vodacom consultants but none of them could explain why the sudden migration that I was not made aware of. I was also told that they would not produce a credit note for the overpayment I have made. Putting people on subscriptions that they did not agree to. And then being rude and trying to hold them to those subscriptions is total *****.
