Got a gift card through blue light card as it had 5% discount and bought loft insulation. Later realised I didn't need it and returned the lot, which was an ordeal in itself as had three missed collections! So days off work, all day waiting etc. Then had to go in store to get a Credit note. You can't use the credit note online so went to order from the shop. You can't use to buy bulk items that come from third parties. Had to buy in smaller quantities to be able to use credit note, which cost me £46 more than ordering in bulk! Credit note expires end of 2025 and still has £ 210 on it! How am I going g to spend that amount in B&Q in 9 months?!! Absolutely appalling. Can't get a refund neither, stuck with it. Worst company ever, treats customers like dirt when there's a problem. No need to say, after this credit note I'll never shop in B&Q again
