not paying when it should

Discovery insure VitalityDrive rewards where you can get up to 50% of your fuel back has system issues. For November i never received any cash backs in the december and when i called discovery to sort out, they said it will be paid over with my december cash back on the 15th of January. January the same thing happened and now they are saying i will receive it all with my January cash back on the 15th of February.<br> <br> It is your fault not mine why do i have to wait another month just for you to mess it up again!!!!!!
