Poor customer service

I recently signed a contract with MWEB. Before committing, I inquired about the process for relocating to a new area. I was assured that all I needed to do was inform them, and my service would be transferred to my new home. However, upon informing them of my move, I was advised by a salesperson to cancel my current contract and start a new one. When I asked about the penalty fee for cancellation, I was told that no penalty would apply to the products in my current area. To my surprise, I received a statement today that shows a penalty fee. When I tried to contact their call centre, I was transferred from one agent to another without any resolution.
