I am writing to inform you that Quidco has taken the decision to suspend CDWOW from the site. This is the result of repeated requests for payment from them to which we have had no response.
We take this type of decision very seriously and we are holding an internal investigation with input from CDWOWs affiliate network.
Please be aware that we are doing all we can to resolve this issue but at this stage I think it is only fair to advise you that Quidco cannot guarantee that cashback will be paid for any outstanding transactions or payments for this retailer.
I apologise sincerely for any concern and inconvenience that this may cause and as soon as I have more news I will contact you again.
