Worst cancellations department ever!

I am very disappointed in the Discovery and Vitality team. I was on the 3 months free trial for Vitality and callled in on the 2nd of May to cancel it telling the consultant that I never used it because I don't understand it and I am cancelling cause I don't want to pay for something I don't use. The consultant went and cancelled it for end of May after I told him I don't use it and he told me I wont pay for it. Today I had to call in 3 times spoke to the most Rudest and Useless Cancellation consultation that not only gave me the wrong email twice but refused to help me in anyways and just want me to send a email but keeps giving the wrong email adress?! I honestly dont know what to do and the consultant is no help what so ever!!!
