Is it at the retailer/Manufacturers discretion that they refund or replace? Bosch have said if I want a refund they will consider it, but they would pro-rata the refund based on it's age.
Doesn't seem right to me. The retailer is insisting it's at THEIR sole discretion as to whether they offer me a replacement or refund. I thought it was actually my fault.
Given we have been dealing with this since September, I have zero confidence in the post sales service from Bosch, or their appliances, getting another one isn't likely to significantly improve the situation so why wouldn't they just refund me and let me be someone elses problem?
I think it is at their discretion. And for them to offer a new machine after you have been using the old one for three years is a very good outcome IMHO.
When you first noticed the issue, Bosch requested to take the machine back to look into it the fault. You said no, and continued to use the machine for several years before going back to them. My view is that when you said no for them to look into the fault, you lost any leverage to demand a refund at some future point.
I'd look at this glass half full, rather than glass half empty. Bosch are giving you a brand new machine to replace a three-year old machine. I think that's a pretty good outcome.
