I borrowed a grinder from someone on here a couple weeks ago to free my bike. Took about 5 minutes to cut through because of the position, I wasn't able to hold still the lock. If you can kind of clamp it, it'll take 30 seconds. Hell of a lot of sparks though.
A picture of you with the bike from the past may help if you don't have proof for the frame
