Speak with the source that supplied the phone to see if they'll supply a replacement or speak with Samsung Customer service to see if they'll send you one under the manufacturer warranty.
Maybe as an alternative look at wireless chargers too !
I wish you all the best with this @AlexHillan84

@AlexHillan84: If the phone is under 12 months old then you can arrange for a replacement charging cable to be sent to you under warranty. With this in mind please reach out to our Help Desk via the link below, or contact us on Facebook or Twitter, and an advisor will be able to look into this for you. Please have your proof of purchase to hand, as this will be required to verify your warranty. I hope this helps.
any charger from any other phone will work, as long it's USB-C, super fast charging works with a huwei 40W charger and fast charging with a xiaomi 30W charger too ,
but if you need just the cable, like suggested go amazon and search for 'USB-C to USB-C' cable
