Yes, I'd become rather used to the 1.3mbps up speed. Now, after the SNR was reset, I'm getting 679kbps, which is better than the 519kbps I was getting before. I'd happily drop a couple of mbps on download to get my old upload speed back, though.

Did you move to TTB? If so you can be reassured to know it's not a Vivacity thing, I had exactly the same upload outcome when moving from O2 recently but with a different reseller.
It is a bit frustrating when you know your line can deliver more, though I've not found it to be an issue in practical use.

I asked about that, got this reply: Only on an annex M service and this With your current stats I think there is not enough signal there to raise the upstream and would cause the entire connection speeds to drop.

I don't understand the last bit, I had a stable connection with the 1.3MB upstream on the old package, no probs at all apart from what I assume was occasional congestion that knocked my speeds down now and then. Since the changeover my browsing is laboriously slow, akin at times to trawling through treacle when compared to what I had before. Not much to be done about it though, at least the connection seems stable, that's the most positive thing I can say. There's hardly anywhere to migrate to that offers better upstream, better the devil you know and Vivaciti are a decent company.

Annex M works differently to just having a higher upstream on Annex A.

Whilst that may have been fine, Annex M might not be.
