2 recent experiences  with major bookies , one with Betfred  over an account discrepancy , their response after several phone calls ....is to totally ignore me and hope i will forget about it .

...and one  with stanjames , which even though initially it was my error  for not completely reading the terms and conditions , because they failed to get back to me  and  i rang to complain about that , they give me a free £30 


. 
So begs the question , how can 2 major companies treat their customers so different  and why ? 
Whats been your best and worst experience of customer service with a bookie ?
