Not happy!!!!

I received a call from an agent on the 10th of November 2022 offering me a deal and a migration of my current package. I was then advised that I would need to cancel my current one because I would be getting a new one. When I called vodacom to cancel I was actually told that the deal that was sold to me on Thursday was actually declined and I wasn't advised. I'm left inconvenienced now coz I canceled my package for a new deal that was declined. What kind of service is that????
