Toner cartridge for OKI MB460 bought for stock. Installed when the old cartridge ran out 15 months later.
Cartridge had a faulty or incompatible chip.
DoItWiser refuse any refund or replacement because 'out of warranty'.
They ignore their duty under the Sale of Goods Act to deliver items of merchantable quality. Compatibility chips do not fail when unused in storage.
Outside Amazon's 60 day returns policy so - is it worth going to Trading Standards or County Court for £20?
