CFM Rewards

I activated my card over a week ago and was supposed to get a $.20 off per gallon up to 15 gallons discount immediately upon activation and an additional five cents off per gallon the more you purchase. Never got $.20 intro and spent over $700 in fuel the last week and not one transaction has gone through with the rewards card. Every time I call the number it rings three times and goes to voicemail and have not got a single returned call. This Has to be a total scam
