Customer care agent **** to me

I called their callcentre on 25May and spoke to Ayanda asking to cancel my membership. He convinced me to stay and pay a reduced premium of 145 for the next 3 months and maybe after then i would have changed my mind. I agreed to it. I asked him effective when is this reduced fee and he said 01June which was perfect for me. He also sent me a mail confirming this new arrangement. On the 2nd when I checked my bank statement I realised that they debited the usual 291, meaning that what he promised me was a lie. I responded to the same confirmation mail he had sent me, asking for clarity on this and I never received any response. Virgin Active please cancel my membership and refund me the 291 you debited on 01 June. I'm no longer interested in anything you want to say to me.
