Terrible experience with Webafrica

I subscribed to Webafrica last year as service provider it started with r499 per month which they didn't tell me it's on promotion 2months later I received email that my promotion is over that my next billing will r699 per month which I didn't mind. Two months later they increased it to R829 and the package I signed from the beginning is 25mbp/25mbp which never changed. Then on may 2023 I received email that I'm owing may payment that my service will be canceled then I spoke to one their agent that I'm owing r16660 if I'm not mistaken I told then I will pay R1000 then I will pay remainder later then on 30th june my subscription canceled and I log in and I discovered that they want to debit my account of r3546. Then I decided to speak one of their agent, they told me I'm owing r3546 which I'm amazed, then the agent asked if I want to continue using their service that I should pay r575 they will reconnect me again then I will continue to pay R829 then r3546 will be canceled I told the agent I'm no longer interested in their service. The asked me important question if during my subscription they told me they will be hidden I rep**** no. This is outrageous of Webafrica people should be careful with these service provider bc R829 is too much for 25mbp.
