What pizzed me off recently was getting something from Next for the first time on-line - then three weeks later, a delivery truck turns up with two very substantial tomes weighing some five to six pounds, their catalogues for clothing and home.
Then the next statement a charge for £3-75.
I e-mailed them and this was soon retracted, my argument including (i) I had not requested it (ii) I had ordered on line so could obviously access the on line info and (iii) they were very welcome to arrange removing it.
The rebate promptly came through to be fair to them, but the chutzpah in the first place...
