Unrecognized Payment and no live agent support

Hello there i have an unrecognised £105 payment to JD sport Internet (where I have never purchased from) last night 10pm. I was trying to get connected to a live agent however no one responded over past 12 hours. What should I do? Any help please? thank you.

Tap on this operation, then go to the very bottom and tap “Something wrong? Please contact us!”
Then “I don’t recognise this payment”

I have the same issue, £200 split over 5 payments made to Alibaba.com but i have not bought anything from them. It has been 8 days sonce i contacted agents in chat and still no response. Shocking service. Revolut is not a secure platform
