Awful Customer Service I have shopped frequently at M&S and thought they were a brand to be trusted for quality and integrity. No longer! I took some items back to the Lakeside Thurrock store but had put them in the wrong M&S bag and hence had the wrong receipt. Rather than waste a journey i accepted a credit receipt for roughly £90. I used around £40 on food and saved the last £50 to buy something nice for myself. I did not study the credit receipt and didn’t realise they only last 1 year. Last Sunday i tried to use the credit receipt against some clothing and was told it had run out and the money was lost! I was advised to go to Customer Service but they told me they could not help and to call head office. I duly called Head Office Customer Service and was passed from department to department (mostly South African, then eventually in the UK) for 39 minutes, only to be told nothing they could do, and the phone went dead mid conversation. They did not call me back ( by now i had no idea what department i was speaking with). I then called again and after another long delay was told by ‘Julie’ nothing they can do, write in ‘if it makes me feel better’ but it would not make any difference. I am just flabbergasted that i can hand back £50 of goods which are then resold, but i am £50 worse off with nothing to show for it. How can M&S justify witholding money when i have returned the clothing? I did not ask for a refund - i asked for a voucher which I can then use instore. I have built up over 61,000 Sparks points so M&S can quite clearly see I am a regular loyal customer. I am so disappointed than I no longer. wish to shop in any of their stores. I have written to head office to give them the opportunity to put things right but sadly unless they re-issue a credit receipt, there are lots of alternative stores and they have lost my custom forever. Come on M&S, pull your socks up!
