Wish complaint: Did not receive delivery

Hermes delivered a parcel a month ago have admitted fault that it was not a compliance delivery as they left it unsecurely at my front door on an open Street. Subsequently when I returned home the next day the parcel was gone. Because the courier marked it to wish as delivered wish are doing nothing about it despite a months worth of emails to them back forth from myself Hermes (see below photo of latest email) Hermes admit full fault, but say wish must refund me then claim from them. The customer service from Wish has been absolutely atrocious. I am an avid wish customer stupidily even purchased again with wish last night, but I am fast losing my patience with the incompetence total lack of customer support shown by wish on a very simple matter, of which Hermes have been helpful from the start admitted full fault. It beggars belief to be honest.
