Wickes Extra Swansea. I had a voucher for a tin of Hammerite from the manufacturer, Akzonobel, due to a problem with a previous purchase of the product. Great customer service on the part of Akzonobel. Voucher could be used at any store stocking their products, in this case HAMMERITE. The voucher and instructions were quite clear to anyone who could read. A blue voucher to place in the till, by the vendor and a pink voucher to send to the address provided by Akzonobel on the voucher booklet both on the inside front page and the back inside page. Simple or not? 40 minutes in the store while various mangers were called and none knew what to do with the voucher, and then a further wait whilst another member of staff waited on the phone to ask customer services how to process the voucher as, " they had never seen one before"!! Absolutely disgraceful customer service with the attitude, I will pass this on to as many people as possible to make your life difficult so that you may just go away,BECAUSE....... I haven't a clue what to do. To top it, I was told that they did not have a stamp to authenticate the voucher that needed to be sent back to Akzonobel WHAT?!!!! I do not live local to this store so I wasted 2 hours of my time today on a fruitless and time consuming visit. Appalling lack of customer service and use of brain cells.
