Yes exactly. They won’t respond. You can fight it easily as you know you didn’t get anything. Check the IP address and too as usually that doesn’t match, and add proof the IP they’ve got is wildly wrong. Track it and it probably won’t be anywhere near you.
Ask them for the proof of delivery to your email because there isn’t an account login on their site so the only way of delivery is via email, so original attached copies of those emails or links to access the images to prove they delivered as you have no records.
sometimes the PAN is wildly wrong too, not sure if that helps.
all of this together they have no chance.
good luck!
