Right well I am no further forward so I am now contacting the networks.
For those that are interested, and may want to check for their unique codes, the site that I have issues with is MyVoucherCodes.co.uk that is registered to RosesByDesigns.
RosesByDesigns is here on the forums, and has been online since I messaged him (Mark Pearson) but have not received a single reply to my requests.
My pinched codes can be seen in google here;
site: myvouchercodes.co.uk coldsnail - Google Search
It maybe worth you checking your personal/unique codes by changing COLDSNAIL to whatever you usually request.
I am now off to the following networks & merchants asking them to act;
Coles Shirtmakers - Webgains
Half Price Perfumes - Webgains
Not Designer - POR
Truffle Shuffle - Affiliate Window
UK Soccer Shop - Webgains
Uplifted - Webgains
