AITAH for telling my partner to wait until my break to help with something because I WFH at a call center and can’t risk missing a call?

I work from home for a call center so Calls are random. there’s downtime, but you never know when the next one’s coming. and my job has recently started cracking down on missed calls. I’ve already missed a couple so I’m trying to stay on their good side.

Today my partner asked me to help put something in the car. I said it would have to wait until my break. Not “no,” just “not right now.” They responded with “you got all these excuses, you’re not gonna get fired for missing one call.”

I’ll be honest , part of this is on me. When it’s slow I’ll sometimes offer to help with quick things around the house. So I get why they don’t fully see it as a strict work environment. But the problem is they don’t understand the nuances and seemed to be entitled to my assistance being in a WFH environment. . One missed call in a call when they’re already eyeing everybody for puts me on the hot seat and im the one who has to deal with that
