Poor service of the rewards department

I have contacted clientele rewards to claim thr travel reward by means of booking a bus. The agent is so rude and unfriendly telling me to read the t&c about the 24hr waiting period to book a bus. The terms and conditions of the rewards for booking a bus does not state 24hr waiting period. It says proof of payment must be faxed or emailed to receive the booking confirmation code. I phoned 4 times and the very same agent answered and keeps on slamming the phone down in my ears. Shame on you u clientele thats not the way to treat your clients that would like to make use of their rewads
