Fuel rewards a gimmick

Vitality drive rewards us a gimmick. I logged a query regarding the short payment on my July payment. I spent R800 and qualify for a 50% reward. I called the office and was told to wait for someone to contact me. This is not acceptable, a company that advertises broadly about their rewards program yet they don’t advertise how they hold back payments, if you don’t query you won’t get paid! Imagine the interest Discovery is earning on rewards due to customers.
