Will my return be processed before my next flex payment?

I mailed back a pair of Bearpaw Millie boots because, they had glue droplets or some sort of stain on the heel of one of the boots. I can see that my return was received back to the HSN Return Center on February 24. So it’s been there for 5 days now & haven’t gotten a refund yet. I have a flex payment due in less than a week….will be return and refund be processed by then? What’s taking so long for returns to be processed? It’s really unacceptable to take this long to process simple refunds & no other company takes this long with returns / refunds. 🙁
