Bose failure

A few years ago I bought a Bose Soundlink Mini Bluetooth Speaker. I am in my 70's so didn't really use it very much. It then failed so I contacted the local agents only to be told to speak to London as they had no backup service here in Cape Town. So I left it. Lo and behold a friend bought a later model and this has also failed! - We went in to the local dealer to see what we could do and they said they now had a workshop here. It would cost us R500 each to get them to look at it and then they would quote to fix it. Long story but how can a brand like Bose have 2 failures of a supposedly high end product (which cost us each in the region of R4500). It wasn't the service of the staff I am getting at - its the reliability of the product!! I certainly will not entertain buying a Bose product again
