Shocking service

I had a problem with my HP Office Jet Pro 8600, which is a little over 1 year old. It seemed that the Print Head had gone.<br> <br> I originally called the supplier that I was given for Durban, SPL. After giving them the product no. etc. they said they had the part in stock. I travelled all the way to fetch the part only to get it home and find out it is the wrong part. I have still not been refunded. My problem is that I was not able to get a part anywhere in Durban through any of their suppliers in less than 8 working days, unless I was prepared to spend a fortune with a supplier in JHB. I was then told by HP's repair company in Durban, Ensure IT Services, that they would most likely still honour the warranty as it was within 30 days after the warranty expiry and that I should phone HP. I did this while I was still at Ensure. I first got through to a really helpful person who confirmed this and put me through to the Service centre. The person I spoke to had a huge attitude and first attacked me as to who told me this and then proceeded to be rude and told me that they would not honour the expired warranty.<br> <br> I have sent 2 complaint emails to HP and have to date not received a response
