False Advertising

When i signed up with Dial Direct, i was told about the application for driving that you would get rebates for the month. I did my trips for the month of August 2018 from the 1 August to 28 August. I had 8 valid trips for the application. Then on the 1 September the applcation said i had 6 valid trip removing the 2 valid trip from the 1 August and the 2 August. I then called and spoke to their consultants and they said the their applcation only records trip from the end of the month and 28 days backwards. They said that it was in my terms and conditions. But i was told by the sales person the it was for a month. This is now false advertising which is misleading to DialDirect customers.
