Personal data given to netflorist leaked/sold

My complaint is about the (lack of) protection of my personal information.<br> When I set-up my account with Netflorist, I used an alias of my email address that I only gave to them. <br> I started received spam from Wantitall which they have sent to the email address that I've given to netflorist.<br> I called and spoke to Y****a on 22/01/15 who told me a supervisor wasn't available and that I needed to email her with the details, so she can pass it on. I did just that and nothing happened. I follwed up on the 23rd with no response.<br> Please netflorist, can you provide me with a reason as to why WantItall is sending me email to an email address that I've only provided to you?<br> This is an extract from your privacy policy on 29/01/15: \The contact information we collect will be used to contact you to query or complete a delivery where the recipient cannot be found
