Earlier this week I signed up for Sky and went through quidco (which tracked) to get cashback and the £100 M&S voucher. They rang me up today and said that the order had failed but could not give me a reason why(?) - he said it could be an issue with their website. They agreed to give me £100 credit instead of vouchers but could not do anything about Quidco. He said Sky are continually trying to not be part of these referral sites and it has nothing to do with them which is what I dont understand? What should I say when they ring me back? I really want to move away from Virgin but want some premium channels like Sports so will have to use one of these companies, what are my options??
