I'm sorry to hear your experiencing issues with your Samsung phone 😒
When I had an issue with one of my phone's my Samsung Experience Store and a Samsung Service Centre managed to resolve this in a couple of days.
Repair times can depend in availability of parts and engineers time due to any work load in front of your repair.
If a phone has been owned for less than 30 days then Samsung replace it.
After 28 days they would insist on a repair under the Limited 2 Year Manufacturing Warranty.
I appreciate you don't own a back up phone.
Would it be an avenue to ask family, friends or work colleagues if they have a spare phone sat in a drawer that will accept your network sim card you could borrow until yours has been fixed ?
Samsung also offer a Doorstep Repair for eligible phone's.
I wish you all the best with this.

Samsung repair service is absolutely abysmal. My phone screen cracked (totally my fault), sent it in for repairs on the 9th August for new screen (not under warranty). I have had to continually follow up with them, and every time I do follow up, I am told "We've ordered parts".
Samsung have had my phone now for 21 days and no end of resolution in sight. I have asked them to send me my broken phone back (it still works, just a cracked screen), and I'd prefer having a cracked screen phone compared to not having a phone, which they seem to be happy telling me I should just suck it up.
I escalated the matter to the manager, the manager was supposed to phone me on Saturday at the agreed time, which they did not, they decided to phone me on Sunday. The manager advised that she would get resolution within 48 hours and email me. Again, this did not happen, and I had to go to support again today, and they say "we are awaiting parts".
Absolutely disgraceful service from Samsung, for a premium S21 Ultra phone. What's the point of paying premium if you get shoddy after care service.
Stay away from Samsung Repair service is the only advice I can give you based on my experience with them.
