FAULTS & FAILURES
There is a major failure with a product when: you would not have purchased it had you known about the problem/it is significantly different from the description/sample or demonstration you were shown/it is substantially unfit for its normal purpose/it is unsafe.
For purchases with major failures you may reject the goods and get a refund or an identical replacement.
Minor failures include small problems with products that do not fit into the major failure categories, for example, loose threads on clothing.
