Hi Coffee Shop, your encounter is sounding very much like emails that have been sent to me. Are you able to let me know if anything came of it?

Phone number provided to us after a lengthy email back & forth. Has requested that we charge exorbitant amounts of money on a credit card they have supplied us, under the guise of it being a pre-paid lunch booking for a birthday party. The requested amount goes WAY over what we have quoted for the group, and they are wanting us to process this ASAP, with a bonus tip! (yeah right). Have yet to see if they will leave us alone, and have reported them to the ACCC. Phone number untested - apologies to anyone who actually owns this number!
