BAD SERVICE/FAULTY MERCHANDISE

I purchased an HP Officejet Pro 8600 for our business in January 2014, it has been back 4 times in the last year for the same fault, leaving my office without a printer/scanner/fax for 10 days at a time. <br> The first incident occurred in April 2014, when they switched the printer on in the store, it printed correctly. The second incident was then later in April when I was informed by Trevor that they cannot refund me and he HAD to book the printer in for repairs. The third incident happened in November 2014 when I again asked for my money back or a new printer and again Trevor told me he cannot do this, if the printer comes in for the same repairs three times in a row, then only can they refund or replace the printer. The printer head was replaced. Now I have taken it back for the forth time on 28/01/2015 for the same problem and they say it's now become my problem!!!!!<br> To date we have been unable to resolve the issue and have been given conflicting information by the staff and the Manager regarding warranties and CPA we also have been unable to contact any senior member of Incredible Connection and I still have an office without a working printer.
