False information provided by their sales representatives

The worst experience ever,Not understandable why they lie when making you Join.I joined with Virgin active loftus on 28 May but asked if this can be processed end of June as i have an active gym membership elsewhere which when my contract was presented i was asked to pay Joining fee which i did but 3 days later a debit order went through after calling the gym to find out why i was advised to reverse on my banking app .following day my Virgin active app is blocked whilst i was told its being sorted till today its not sorted and when i reach out to the consultant she no longer responding to my text.That is a breach of contract from their side and I would like to cancel this membership with immediate effect
