Pathetic service with no feedback

Discovery insure had an issue with their system in August where points were not allocated for night driving resulting in reduced cash back. I contacted discovery regarding this and they found it was due to a system error affecting many clients. After trying to get feedback 4 times and each time being told someone would get back to me within 2 days and never does, we are now 5 weeks later and no one can even tell me when this will be rectified. The only thing they can tell me is that it is with the developers. What a useless answer. Discovery sitting nicely with so many customer cash back money in their account earning interest
