Considering how low are the stocks now, I'm not surprised.
Few manufacturers anticipate issues faster, like EVGA regarding the dying 3090's but, sadly, I'm not surprised.
Another thing to take into consideration now is how anything that isn't fixed in the UK is likely to suffer some delay, due to paperwork.
Just as an example, every now and them, when returning anything from Amazon EU, no issues. Now only UPS, few extra paperwork and ages to get the whole thing processed.
In your situation, I would wait, unless you manage to get a cheap replacement and hold for few months when next gen is coming out or the mining industry collapses.
Not sure if you qualify for a refund, but I would be tempered if you manage to get one of those deals on Overclokers like 3060ti or 3070.
The way things are, next gen is out by the time you get your card back. A refund would allow you to get something from a more effective manufacturer, like EVGA when next gen is out.
I wouldn't invest top money on 3000 series now.
Just downsized from a 3090 to a 3070 and will wait to see how things play.
