I ordered various bedding items online. One item was sent by M&S in the wrong size. Unfortunately the size was not at all displayed on the packaging and the error was therefore not obvious to discover until I had washed the item. Trying to have the item exchanged for the correct size (the bigger one I had paid for) was refused. Apparently they don´t exchange items that have been washed. I would normally agree with this. In this case there was no way I could have discovered M&S errors until after washing. They were not even willing of reimbursing the difference in price of the items. I am totally disappointed by the lack of customer service offered in this scenario. I will not order with M&S again. And this comes from a formerly longterm and happy M&S customer.
