Wrong contract, awful service

A few weeks ago I received a call from someone saying that I needed to upgrade my MTN contract. I asked for a contract similar to the one I had. I agreed to all the terms and asked him to email the documentation to me. I never received the documentation and then a few weeks later I ran out of air-time. Turns out, he gave me a data-only contract(not at all what I asked for). Since then I have been trying to fix this, but they are beyond unhelpful. It's also terrible that I need to spend about 45 minutes just waiting to speak to someone in the retention department. Please change the contract to one that I asked for, or cancel the entire thing.
