Discovery's Ridiculous Average Spend Calculation

I have never experienced such frustration with a simple issue. Calculating an average. My first month with Discovery was Feb 2026. They calculated my average spend by dividing Feb spend by 2. I asked them why they're dividing by 2 and they initially told me it's because of an internal first month rule but it has no impact on me. I clearly explained that it clearly impacts me if you divide by 2 which cuts my average spend by half. And Affects all the respective months because the denominator will aways be 1 higher than it should be thus reducing my average spend.

Their last explanation was that I must scratch whatever they've told me previously. In Feb they divided by 2 because it's the second month of the year. Which is even worse then, it means a member that joins Discovery Bank in October their spend will be divided by 10 even if they joined in October.

These responses are completely ridiculous
