Disappointment!!

Bought M5 360 sound speaker for partners birthday at B&O Silo District. Set up fairly simple but clunky app. Was advised to use wifi connection. Played for a minute or so then stopped. Couldn't fix this so went to Bluetooth. Finicky and connection sometimes hard to establish. Complained to store with great detail and got an email telling me how to set up (again!). A note at bottom of email said B&O was experiencing "no sound situation" with certain products. Of this I had not been warned when purchasing but seemed to be my problem. Unsatisfactory and slow and not very concerned back and forth with store and Joburg management. Asked for a full refund and told ok but a 20 percent surcharge if your packaging is not pristine!! Returned the product and store manager who sold me the M5, slouched in his chair, didn't acknowledge me and his junior handled the transaction. Manager brought me final paperwork to sign. No apologies, no sorry the product didn't work and we didn't know how to fix it. From a high end product pretty weird. Never again.
