r/Sezzle

So Im new to Sezzle maybe a few months in. My starting spending limit was $150. I advanced really quick up to $350 within a couple of months. No late payments and most payments were paid early! So yesterday I made my payments that were due but I used my Sezzle virtual card by loading it up and paid that way. My power was then back at 95.95. So now this morning, I look at my account and it's showing a spending power of $20.95??!!! and says that my spending power is now $250??!! Where's the other $75 and why am I getting penalizedfor paying 1-3 days early??!! Customer service was no help!!
