Haven’t made a PPC sale in ten days!

Hi there! I need some guidance. I got notified that I have excess storage, and coincidentally my PPC ads haven’t made a sale in over ten days. I’m still being charged for ppc though, go figure. I reached out with a help ticket and got some canned answer saying something algorithm this and that but I can’t help but feel Amazon is punishing me for having excess storage and need me to bid higher.
