On **/**/**** I ordered Epson l*** printer through Amazon and received diaper instead of printer for which I raised complain on */**/****. They told me to wait for * days to investigate on */**/** my investigation was completed they told me that item will be picked up by **/**/** however pickup failed due to verification issue, after contacting customer support they ensured that verification will be removed as it was not required despite that my pickup was not done.
