Managed to find a tutor who's also advertising on Gumtree, after she received full payment & only showed up for an hour of the 3 weeks I paid for, she said she had miscarriage. At first I was understanding, but after I asked for my money back, she called me "heartless" and "wished I have a miscarriage". Are these the calibre of people we are allowing to advertise on Gumtree? Disappointed.
