Thank you BankFodder for your reply.
Firstly, they asked me to come in and select another machine up to the value as replacement. The one I chose would take weeks to be delivered, so I asked for, and received a refund.
I was reimbursed for their requested INDEPENDENT REPORT.
It is the £25.00 I am insisting that they refund as well. I told them that instead of requiring me to get the second report, I could have put them in touch with the FIRST ENGINEER who would confirm the findings of Manufacturer's Fault. So it was solely their choice, and that the people in Customer Service should be given a FLOWCHART so as to identify when a product fails within or outside of warranty and therefore falls under not of Merchantable Quality. In other words since I gave them the date of purchase and what was wrong with the machine a flow chart would identify that that component failed too early.
I am not very good at this. I am just using what I feel are appropriate words to get my money back. I do not feel they should use Gift Vouchers to force me to give the money back to them.
I intend to reply and say that 'without prejudice' to their offer I am going to take it further. Can you please, if possible, confirm I can rightfully require Cash ?.
Thank you again.
For the knowledge of those on the site: Because I collected the machine from the store, when it became faulty I had to return it myself, otherwise they would charge just under £16.00 to pick it up from my house. If they delivered it at time of purchase, it would not cost me for them to collect it.
