I am so appalled with Quidco right now. I've had my account with them for many years, earning over £2k in cashback (and even more for them as a result!) and went to log in last week to find I couldn't and my account had been "blocked". Communications with their staff informed me that my account had been removed owing to what they described as "false referrals". I replied saying that I haven't made any referrals for quite a while and could they explain more but they simply replied again saying false referrals were made. I have still been receiving email from them advising me that my cashback has become payable yet they tell me that I no longer have my account with them. I think potentially my account was hacked and I'm now fearing for the security of the site. I can't check this or the account activity because they have removed my account and hence kept my cashback too. I'd warn anyone of this and not to open an account if you do have one remove any sensitive data they hold on you and withdraw any payable cashback you do right away. Dreadful!
