Cancelling of contract

I called virgin active this morning to cancel my 24 moth contract which only has one month left. I currently have a hectic work schedule which involves a lot of travel so i felt it would be best to just cancel it and join again 2 or 3 years time when things are a lot calmer. The agen call center agent tells me I needed to go to the gym to cancel the contract and pay the fee??? Its 2018, everything gets done digitally, I dont have the time to schedule a visit to the gym just to cancel a contract! Can someone at virgin active assist please!
