Dude you really don't have much luck, frankly Id just get your cash refunded and not worry too much about not having a bass that wasn't your first choice anyway 👍
A few of us were in the pub a few years ago and one of the gang described at length the catalogue of disasters that had been his last 10 years of buying new cars, finding them faulty, getting them repaired and/or then replaced. It was pretty amusing albeit not for him (he has more cash than sense being a big part of it). He finished his tale of woe with 'What the f***'s a bloke supposed to do...?", to which came the almost unanimous reply 'Stop buying new cars"
That probably wasn't much help 🤔
