Zoho Books says "The customer "Hakimuddin P A Ali" already exists. Please specify a different name.""

One of my transaction is not getting posted from Stripe to Zoho books. I already checked in Zoho books that there is no customer already present in Zoho books with the same name (as the error mentions)

I already raised this complaint on Zoho flow portal, but I am not geeting any response since last 5 days.

Appreciate your help.
