In tracking page it shows shipment delivered on 23rd march 2020 when i haven't received a single call from their delivery agent and also it shows signed by self, i have not got the package still, what kind of fraud these people are doing instead of delivering the package on time they put it as delivered in their tracking page just after two hours from their out for delivery status.
Still haven't got any package from them and still mailing them but to no avail.
