Recently got several charges from taskrabbit on my card statement for jobs/tasks I never posted I knew nothing about. I disputed these charges and the bank refunded the £££, but taskrabbit has insisted that the jobs were legit and that I supposedly authorized them, even though they were done in a different country by someone I'd never heard of. Tasker "Antony Nwosa" supposedly spent 5.5 hours assembling a wardrobe in Dartford UK, but the job was commissioned at 12:58pm and completed at 2:00pm - so could not possibly have taken 5.5 hours. But taskrabbit didn't think that's fishy at all... Couldn't be any more obviously fraudulent, total scam.
I'm sure there are some genuine people trying to earn a living through this company, but it looks like others are abusing it to steal or launder money. Buyer very much beware!
