Baxi heat exchanger - 7 hours to fix (+ phone calls...) and leak still there

We've had a nightmare with our Baxi Netatec combi boiler during lockdown. It started leaking, so we got the engineer in (we have a home repair contract). He replaced the air vent first off, went off, leak got worse, he claimed it was the heat exchanger. So he replaced that, which took 7 hours and involved several phone calls. Things have escalated from there (via an alleged pressure problem which resolved itself as soon as he went...) and when we questioned the guy's credentials, the contract company sent a second engineer to look things over. Engineer 2 implied that engineer 1 should have fixed the heat exchanger more quickly (raised eyebrows at 7 hours, "did he look like he knew the job?") so my question really is whether that's true: how long do heat exchangers typically take to fix, and is it the kind of job that a qualified engineer would need to phone for advice on? Six weeks on it's still leaking and the company has said it's not their fault. I've read on here that we basically need a new boiler, but if he's messed things up we'd like them to pay at least some of the cost. UPDATE 1st July: Thanks to SMIDT for the answer and the video link (definitely worth a watch). Baxi rang this morning: it's the DHW Plate Heat Exchanger that was replaced. Their estiimated time for this job is under an hour for one of their own engineers, 2-3 max if the engineer is unfamiliar with Baxi. Even factoring in some optimism, 7 hours seems a stretch. No time given on the 11 minute edited video, but the bloke started at 3 pm and wasn't complaining at the end so I'm assuming it wasn't 10 pm when he finished...
