My Canon Printer Keeps Showing Paper Jam Error

My Canon printer keeps displaying a paper jam error, and despite trying everything, I can't fix it. I've been trying to reach the Canon service center for hours. After waiting on hold for nearly half an hour, the call gets disconnected right before I can speak to someone. It's disappointing that a major company like Canon can't establish a proper service network or call center team. How can you be so ineffective? I will never be a Canon customer again. I urgently need a call from you to resolve my issue. I haven't been able to print anything for two days.
