WORST Customer Support Call Centre

Should you ever wish to cancel your Virgin Active gym membership, do so with caution. As per your contract, you are required to cancel, in writing, 20 business days prior to requested cancellation/end date. My ordeal began when I emailed the webadmin contact to notify them of cancellation and received an auto-response apologizing for any delay in response due to high volumes. After I did not receive a response after a week, I called the call centre on 07 February and spoke to Natasha. She informed me (as per her manager) that the cancellation would be dated 20 working days from the date of my call, which I disputed: as per my contract, cancellation must be sent in writing and this was done on 28 January. I then followed up on this point today (21 February) and spoke to Mandy at first - I have never experienced someone in CUSTOMER SERVICE who is less equipped for the job; she was incredibly rude telling me "you need to listen to me" and then promptly put the phone down on me. I called back immediately and spoke a helpful lady (Cindy) who offered me her manager's email address so that I could forward the original cancellation email to her. Now I wait... again. Not holding my breath.
