Poor service

I ordered an items from Wish.com in February 2020. Understandably due to COVID there was a delivery delay. Now months after lockdown still no delivery. I request a refund and they say window for refund closed although it’s noted on their system that items have not been delivered. When I try deactivate the account it refuses to authenticate me and deactivate. Now I have no refund and an account that refuses to be deleted
