Wish complaint: Refund

I ordered a tablet with gps. The tablet does not have gps so I need to return for a full refund including postage as it was falsely advertised. Initially the wish customer support offered me a 20% refund which I declined but for some reason Wish thought I’d said yes? Anyway this has now been going round in Circles for weeks. Wish keep telling me to re submit a ticket through the wish app for the disputed tablet. I keep explaining that the wish app won’t let me submit any more tickets for the tablet. The answer I get from wish is ‘ I need to submit a ticket through the app’ even though I have explained numerous times the app won’t let me.
It seems to me that wish are purposely delaying this so it goes beyond the 30 day refund window.

I do t need a tablet without a gps, I’m out of pocket and I can’t afford to be. Absolutely disgusting customer support.
