Does anyone know if this vendor is legit- not replying back to me and paid yesterday!!!!

Hi people. I’m new to the online services provided here as I always had a very decent vendor to visit local to me.
Unfortunately things have gone very downhill since lockdown began so I started scanning web a few months back in the hope that I could find something and came across LB and was amazed at the variety and quality of service available here.
I am pretty nervous about getting stung so have not actually used the service yet. But I now am ready to dive in but am still pretty clueless about Bitcoin and how it all works although there are many noob advice articles which seem to show the way.
Anyhow I have setup a Coinbase account and used my drivers license for proof of ID but am still unable to use Coinbase as it says I am still being checked out,which seems to be taking an age.
Can I still make a purchase without having an account for Bitcoin ?
If so I think I will try a few samples first if any friendly LB peeps can recommend any particular vendors. As I say this is all very new to me.
I do love a good quality hash so this will be my first choice.
Soz if my post repeats the same theme as many others and I do think there is a wealth of info here, which is nice.
I was lucky in the past with local clues but these days I seem to have lost touch with so many people that LB seems to be my best bet.
Thanks for your patience with my rambling.
Rob.
