I received following email by a venue in London:
We are getting in touch as we are afraid we have had to refund your ticket for the event tonight. One of the artists performing has brought to our attention behaviour online that has made them feel very uncomfortable, and for their wellbeing and safety we have agreed it is best for you to not attend.
I responded with the request to provide necessary evidence to make such a serious allegation. If they don’t provide any evidence, is there something I can do legally? What time frame should I allow them to provide me with the evidence? Calling someone a threat for someone else’s well-being and safety without proof and singling me out of attending a concert is falsity, no? T&C and the fact they refunded me would not apply here in the first place, correct?
