Monthly Payback not paid

Good day

I changed my car on the 28th Feb and called to change my details to get the new car insured, I was told to update my app which I did after doing so my cash back for March was 0.0 and before that it was R186 another thing that changed my my cash back booster which was due November 2021 but now it has moved to November 2022 not sure why as I was just changing cars not insurance. today is the 12 April and I'm due the cashback for April of R274.72 which should have been paid back by the 9th but still not paid, I'm currently paying R1212 which I also feel its too expensive anyway i'm considering leaving dial direct i got a cheaper premium and excess but chose to stay with you because of the monthly cash back, might as well change since you have nothing different to offer, I have been insured fr 4 years 4 Months since I've had a car and have never claimed i feel this is just too much and not happy that I haven't received feedback from you guys.
