Extremely slow turnaround time for laptop repair

I have no complaints about the repair job. Although the cost was expensive, that, too, is expected with an HP product. My complaint is the poor customer care and lack of urgency. I needed my laptop to be repaired; I use it every day for work and home. The quote was 7-10 days for spares which is, in itself, a huge problem. As the *only* repair centre authorised by HP, surely they can do better than that? And it got much worse. After hearing nothing for three weeks I requested a full refund. It was only at that point that things happened; my laptop was fixed withing 3 days. Of course, the email arrived late on Friday, and they never answered my email if they work on Saturdays, so I finally fetched it on Monday, 26 days AFTER paying for the repair IN FULL. I find this extremely unprofessional when providing a service for equipment that is in urgent need of repair.
