the owner seems to have posted a decent reply
i can only go on what's been posted as i was neither there nor have ever had any dealings with sid company, i don't even know where they are
but as a customer, i would probably have done the same thing, posted on the net that i was pissed off and let things go from there
tsc seem to have a few customers that speak highly of them so it owuld be a shame if things could not be resolved amicably
as martin has said, booking a dyno for a specific time has always been a bit hit and miss because you don't know whats going to happen beforehand, i went to the dentist earlier this week and had to wait 25 minutes after my appointment time, and i'm going back again today to get the work done that's needed so i'll look back and tell you how long it took this time
