Laptop still not working

I received my laptop back on 19 September after a 4th hard drive had been replaced and I cannot use it. I battled to reload the software supp**** with the laptop. I can get onto the Internet, email and I can get into Ms word, but not excel.<br> I took the laptop back to HP headoffice, only to be put on the phone to a chap at the workshop company in Cape town, who asked me to email all the previous job cards etc, which I did. This chap was very helpful on the phone and he emailed me,copied in, in an email to HP Rivonia asking them to check all the attached documentation and to get back to me. Hp already had all this documentation from me after my first complaint. <br> It is now 1 November and I am still waiting for a response to the email sent through.<br> I have never experienced such shocking service from any company before. They clearly do not care about the customer or the bad product they sell. I believe that Hewlett Packard should refund me the amount I paid for the laptop and the hard drive I had to pay for
