Laptop Repair Taking Too Long – What Should I Do?

I had given my laptop to Ryhum House for repair (as I mentioned in a previous post), but it has been a long time, and it’s still not ready. I’ve called the engineer multiple times, but he keeps saying he needs a little more time.

I understand that repairs can take time, but this delay seems excessive, and my work is piling up. Should I take my laptop back and give it to another repair shop? What are my options here? Any advice would be really helpful!
