Fray Bentos complaint: Inability to open

My complaint:

Bought `Steak Kidney Pie` emergency stock. When deciding to use two of my tin-openers made no impression. Tin recommends a particular brand, which looked the same as mine.
Price on line c£10 to open a ££.75 item – with no guarantee the would do the job.
Spokesman offered vouches; no thanks! Will not buy any products of this company again.
Potential customers shoulllld note this and other complaints before purchaing.

Suggested solution:

Well they could take the product back refund but would only issue vouchers which may well put me in the same position.

Will offer to a food band hope someone is adept with a chisel
