Agree with the sentiments above, more trouble than it’s worth this for the operators. I too haven’t received some of the above and when queried with the programs it’s a case of oh sorry, here you go - now crack on and change everything to suit.
From speaking to one operator last year, a large proportion of the one-off punters don’t use the free bet if there’s still one offered, and if they do they’re more likely to be a more regular punter - so where’s the issue?
