I bought a PAYG mobile from Three (who I would not trust as far as I could throw them - as two out of three purchases have been declined) which tracked almost immediately.
About ten weeks later it was then declined.
So I submitted an enquiry which then returned....
"Response from Merchant. enquiry unsuccessful - Another Marketing channel was accredited with the sale"
I use a browser specifically for quidco, and if the order did track initially, then how could it have been attributed to another cookie?
Any ideas anyone?
