Unprofessional after sales service received

I am surprised that HP uses the services of such an unprofessional, inefficient company.I was unfortunate enough to have to take my computer into the Midrand branch on 20 August. I had to make 3 round trips (50km as well as about 2.5 hours of my time) in order to get my computer hard drive attended to.I also had to deal with unknowledgeable staff (the front line staff- couldn't tell me that an attempt to back up my data had been made but due to the hard drive being unreadable couldn't be done)
