The seller will text you from a gumtree add, will give their bank account details under a false name and then you will not get the tickets. Fooled with $300 tickets. If this is you, contact cybercrime and report immediately, contact your bank and the seller's bank to freeze the funds. You have been warned.
Scammer - replied to my wanted ad on Gumtree stating that they had Camberwell Market Stall tickets available and then was unable to explain where the stalls were located.
