bin/canister will not open no matter how hard we pull

I cannot open the bin/canister of my Dyson V8 Absolute to empty the contents. The trigger does not budge. We tried the little red latch on the bottom of the bin/canister but it’s blocked. We cannot detach the canister as the top red trigger is blocked. I bought it in June last year so still under guarnatee. Dyson told me to send it to them, which I am reluctant to do.

Any ideas how to open it without destroying it? It’s been a week of pulling the trigger so really fed up at this point.
