Hi. I'd like to return "pest free ZONE" Solar Ultrasonic 360 Degrees Cat and Dog Repeller I ordered on Sept 24th and received on the 25th (Order Number: 240924-8315798). This product isn't working properly and it only works intermittently. Sometimes it detects movement instantly, but most the time I can walk right up to it from any angle and pick it up, without it detecting anything. I've tried charging it by cable (Vs relying on solar charging) but that hasn't make any difference. I was in contact with Sandra Clarke on Oct 7th, and she suggested keeping it for a bit longer, but there has been no change in the product since then and I want to return it. Could you tell me how to go about it? Best Regards, Niall.
