Unresponsive people

Good day, On the 31 January,I wrote an email to SuperSonic WiFi to cancel my subscription. On the 7 February a retentions agent spoke to me and said that my last payment will be end February and the WiFi will stay on until 31 March. Last month another retention agent sent me an email stating that I will have to pay the clawback fee as the contract is for 2 years,of which I know is a month to month,not 24 months. I sent the agent the conversations that I had with the 1st agent.,and sent emails to people higher up.up to date nobody is responsive to the emails that I have sent. What a disgrace that people can't even answer emails.they should not be working, very disappointing experience. As long as you pay, everything is ok,but don't try anything else, that's when you get ignored. This is not acceptable.
