Sportech is the tote machine. If you took it back to where it came from and the machines are switched out and it is over a year, you're probably out the money. I'd go back and try once more but talk to someone with power or who can make a call to somebody, look up the ticket or something. But most likely they will have a rule to point to that says it is too late. (Make them show you that rule in writing.)
Or ask sportech directly:
