How do I get through to UK agent who is not script reading
So I upgraded my package on Sunday which includes a SIM which was supposed to be unlimited.data calls and text as I asked to clarify is it unlimited data because if it inst I do not want this package and they confirmed it is. I've now got.my.sim and emails from O2 and its only 2gb. I have then gone onto live chat to be told don't worry it's 2gb and we double it so it's 4gb then telling them it should be unlimited as you have clearly miss sold this package to then be told That I can ring O2 to change to unlimited for £25. Really getting frustrated now I explained this package is incorrect I am not paying to upgrade to something I was sold so I want to cancel they then transfer me to support team who then take ages and then come up with ahhh I see your having problems with your sim, you shoild ring this number. I then explain no I want to cancel my package. I then get put through to someone else who then calls me Simon which isn't my name and tells me I must pay an early disconnection fee of £973.85 even though this package was sold to me based on lies and I only had the contract for 3 days so within my 14 cancellation period.
So how do I get through to someone in the UK who is not script reading and actually knows there stuff as I've also made phone calls which go nowhere with agents not understanding and clearly reading from a script
