Hacked - Anonymous employee Postmates Fleet Employee Review

Not being able to contact a human person when you are in need of help is verchaly impossible, my account was hacked 3 weeks ago and postmates haven't even shown a concern about recovering my $257.55 . I think that they had someone whom previously worked for them and knows how the system works, someone called me while I was delivering a order and stayed that they were postmates manager and that they were doing a system check and the order was fake so I needed to change my inpho, as I did what they said not knowing that this could be fraudulent, my bank card has a Master Card symbol and minutes later it changed to a Visa symbol and my earnings started disappearing, I tried contacting postmates but you can't Talk to a human you must follow up on line, by this time the fraudulent people may be long gone.
