AIO for being pissed off at my colleague?

So I was driving car parts, warehouse transfers, doing my job as usual. It turns out I forgot to bring some parts for the transfer and I was already at another town 30 minutes later.

Then the colleague from the warehouse who is responsible for transfers calls me and I can’t hear her over the phone, dead silence. I say “Hello? Helloooo? I can’t hear you!”, and 30 seconds later she hangs up and doesn’t call again.

I come back to the warehouse 2 hours later, and then she tells me “Why do you pretend to not hear the phone?”, and I was actually insultingly confused. I was thinking of a scenario like that in my head as a joke, because she is usually confrontational. But she actually genuinely said that with her mouth!

For reference, everyone, fellow drivers, the manager, the sales representatives, any other colleague who I can’t hear, they hang up and they again. She actually jumped to the conclusion I was pretending to not hear her over the phone.

And it has been bothering me for the rest of the night because she actually thought I was playing and not… genuinely not hearing her at all.
