Levis lying to the public with false advertising

Levis has just launched a promotion /sale campaign, where they advertised that all styles were less 70%.So I drove all the way to Durban from Hillcrest only to be told it was a mistake .Only select items are on the sale .The staff there were not helpful and nor did they show any willingness to try and explain the mistake..Being a regional manager of a nationwide clothing chain ,my advice to Levi's,before you run a national promotion campaign ensure you have the correct info .Are you going to repay my petrol and time because of your incompetence and false advertising. Before you send emails to me ,ensure that you send correct info to me otherwise don't bother me .
