In my experience, Quidco can be very hit and miss when it comes to cashback tracking or claims being processed properly if not. They seem to have a list of stock excuses for this not working properly - all which are either the retailer's or your fault; in this case they will blame the glitches in the order/activation process. I have seldom found Quidco Support (email or online chat) much use because of this tendency to trot out generic excuses and to deflect responsibility. However, you might gain some traction via the MSE forum. One of the subscribers there is Quidco's Official Company Rep (currently Joseph) and if you scroll through you'll find his direct email address posted in a number of messages. He also has a habit of trading general defensive lines but at least you are dealing directly with a named individual. Aside from emailing you could also post on that forum where, because any post you make is "public," there is some obligation on them to provide a reply.
