I entered a draw with a reputable company. It wasn't free to enter. The draw was advertised to take place on the 4th of November, but it hasn't taken place. I contacted the company to find out what was going on and just got back a reply that the draw would take place that week (at least 1 week after advertised date). 2 weeks later, still no sign that the draw has happened. Any suggestions on hoe best to follow this up.
