Ordered some stuff just before Xmas that entitled me to an e-voucher to use in the new year. When the item turned up they had sent the wrong colour. Wasn't too bothered as black (instead of blue) was OK and a bit of a hassle to send back, fill in exchange form etc. The e vouchers never turned up though. I chased and received an email saying I would receive them in a couple of days. They never turned up and after a couple of chasers I gave up bothering. At the end of the day it was only a tenner so a trivial sum. So trivial in fact you'd think a retailer would sort it so as not to lose a repeat customer wouldn't you?
