I get that but not if I had reply like this
"Thank you for your reply concerning your replacement request.
I understand you would like a replacement for your RX 7900 XTX. It's important to note that at this moment, we are unable to start the process for replacing your card, as we have no inventory available in our warehouses.
The replacement will be processed once the inventory has been replenished, this will take several weeks. If instead you prefer to receive a refund, we can process this refund immediately"
The email is giving you your options? with a warning that they have no stock for an instant replacement so it may take longer.
With this information you can return instantly for a refund or hold onto the card (but still register the RMA)until they have replacements ready for you.
The alternative was that you send the card back now and then go 4-5 weeks without a card because they never told you they had no replacements....
Also it's been what 4 weeks since launch?
They either need to make more GPUS or rearrange stock and get new coolers on the faulty batches that have not reached customers yet. We've also just had a holiday period in the middle of this.
In an ideal world the coolers wouldn't have been faulty but s*** happens
