Still no reply from curve beyond the automatic response.
Can I deduce they won’t help me?
Hello @Iainm, welcome to the community! 
We advise our customers to try to resolve it with the merchant first as the initial chargeback process can take up to 8 weeks (a timeframe set by Mastercard® to provide all parties sufficient time to investigate).
The support team are getting a lot of messages right now so they’re taking a bit longer than usual to reply.
If you’re currently waiting on a response and it’s been more than 24 hours then I’d recommend sending a DM to @AskCurve on Twitter or Curve’s Facebook page.
