Last year I had 3 referrals that showed redeemed in my account, but I wasn't getting credit for them. I emailed, chatted, called many, many times and they never resolved it so I gave up. I could understand not using the right phone number or some other logical error. But it my case they showed up online in my account as redeemed but they wanted me to provide name, address, phone and acct # for each of those numbers...and I didn't remember who I gave what referral too. So for me it was great for a while and I got many credits...maybe too many since they seemed to stop crediting my account. So I stopped referring.
