Vodacome Fibre - False Advertising!!!

On 25 March 2024 I received an email from Vodacom regarding an update to my fibre speed and price. I did not ask for this, it was just sent to me and obviously I was very happy as this meant my fibre costs would be reduced. The reduction in cost was due from 01 May 2024. When I received my invoice for May I noticed that there was no price reduction. I called Vodacom accounts and they had no idea what I was talking about. I raised with Vodacom again on X (twitter) and Randall from Vodacom said it should be resolved. Today the debit order went off and again, price adjustment not done. I am very confused!!!! How can Vodacom offer me this and now I have to run around and ensure that the offer is implemented. This constitutes as false advertising from Vodacom and I am very disturbed by this kind of communication.
