I got curious and compared odds on the last two cancelled bets at wintomato and bet365 (the world's leading bookmaker).
OP bet 2k on Chicago Bulls at 15:10 with 2.52 odds, while bet365 odds ranged between 2.6-2.65.
Another bet 4k on Indiana Pacers at 8:1 with 1.24 odds, while bet365 odds were 1.2-1.27.
So yes, OP's bets are fine, it's the bookie with lame excuses trying to steal the winnings.
