I know of people who have had atrocious handling of their complaints by sellers.
One in particular seemed unable to accept that there is a law covering the replacement
of defective goods after a year, and went as far as to ban, for life, the consumer from purchasing
further goods, for making a fuss regarding defective items purchased from their store.
Funny thing is they lost out of a lot of future business as additional items were sourced else where, and the company is now on the Lemon list.
Trading Standards did nothing to assist the purchaser.
So bring it on...
