The broken walking foot has been returned to c9stores, where the verdict is that although the generic foot matches MOST low shank machines, the Singer 522 is not most low shank machines.
The patient Emily advised that she could send me a replacement, which would probably do the same thing as the first one, or refund my money so I can go off and buy a Singer walking foot designed for my machine - leaving the rest of the sentence 'which is what you should have done in the first place' unspoken.
She also refrained from saying 'I told you so', which she was surely thinking, bearing in mind that our email exchange prior to buying the foot was whether it would fit my particular model - I decided (quite wrongly) that it would, thank you.
And the money was refunded that day.
I ordered a Singer walking foot on Friday from Sewingparts instead - I've had confirmation that it was packed and dispatched over the weekend.
