    Needed to reverse the latch. Unable to remove one screw - manufacturers had used lock-tight on these screws!! Contacted GB DIY and was assisted by Nathan who was most helpful. Explained the process of replacement and refund. Arranged for free next day delivery as we were going away on holiday and could not secure our back door. Also freed up the screws on the replacement item before sending it. Excellent customer service. An issue with the refund system meant that this did not come through. Chloe, picked up the message I had to leave on the answer phone and dealt with the issue that the refund system had not dealt with. She wrote a very full explanation and her efforts resulted in the refund being issued immediately. Well done to both Nathan and Chloe.

    It was worth the hassle to be dealt with so well by two committed members of staff. Many thanks, Alan Hall
