Dishonest retentions agent.

I wanted to cancel 2 data contracts, was conned by your retentions agent that she will offer me a lower price on a month to month basis. Well, she signed me up for another 2 years. I want you to please listen to the voice recording between myself and your agent, and prove to me that I agreed to a 2 year contract. Please contact me, if not I will just block the debit order.
